Ford Aerostar :: 1995 - Loss Of Power - Stalling - No Codes?
Aug 14, 2011
I have a 95 aerostar with the 4.0. After driving a while it wants to lose power. It only happens after the van has been running for a while, at least 2 hours or more. So of course I have mostly noticed it at higher speeds because I was on the interstate going a long distance when it happened most recently. But it has also happened at lower speeds, after the van had been running/driving for about 4 hours. The van doesn't die right off. It is idling as the van slows down. So I can come to a stop, and the van is still running. I can get out and look at it sometimes, it eventually will cut off. Pushing the gas does nothing, other than perhaps encourage it to stall sooner. It is a complete loss of power but the engine remains running at an idle. If I wait 15 minutes it will go a couple more miles down the road. If I wait about an hour, I can get even further. Let it sit overnight and it seems like it will drive endlessly but not so.
If I try to restart it immediately, sometimes it will run/stutter for a moment. I can wait a few minutes and it will run for a minute then die. After repeated tries to get it to start and stay running it just won't, and then I just wait patiently for an extended amount of time (30 minutes or more). Also on a couple of occasions the exhaust has smelled very rich, and sometimes was black. All of this has been in the last couple of days and 600 miles. It isn't throwing any codes.

3.0 ENGINE - For a year now I could not figure out what was wrong with my van. It has a loss of power low end but seems to run OK at higher speeds. I changed the plugs, wires, cap etc, fuel filter and no difference. I finally broke down and took it to Firestoneto diagnose it. The guy told me #5 plug was foul and had oil on in, said it is possibly the rings. They did not charge me but they also did not do a thorough check either. They did not check the compression in the cylinder or other spark plugs.
Spoke to a guy at the auto part store and asked what I could do. He said change the oil and add a can of restore. Also said to put a anti foul adapter in first and then the new plug, the adapter would keep the oil from fouling the new plug.
I got the oil change and added the restor. Drove it for a while and took the plug out myself, its the 2nd one in on the drivers side. The plug was nasty looking. Put the new plug in and started it up. I can see that there is spark going to the new plug but putting the wire on and off made no difference in how the engine ran, like the cylinder was dead. I took the plug out of the adapter and put it back in, still nothing, I took the plug back out and there was no oil or smell of gas. Fuel injector not working? You would think there would be some combustion with the new plug.
A year ago the problem started where the van would run great one day then crappy the next. Sometimes it would run a few days great(like new) then a few days crappy. After a month or so it just ran crappy and basically has ran the same for a year now. I notice the A/C puts a load on the engine and the A/C clutch will click on and off every few second when the van is in gear but not when the van is in park or neutral. A/C is not low and works fine when driving, very cold. I normally turn the A/C off during take off because it takes off much slower with the A/C running.
The van shows some white smoke when I rev it up real good when I first start it but it does not show any smoke when idle and while driving.

Ok .. here is my problem 86 Aerostar up until 3 days ago ran perfectly. plenty of power, idled great no misses, well the other day i washed her up, inside and out. 1sr time in almost a year (gross) so under the hood i see that the air ducts were kind of loose, so i tightened up the clamps. and later drove to the store and low and behold she won't idle and she surging, forward to today i drove to Wrigley auto store and barely made it. connected to their hand-held scan tool and performed the KOEO test and got a undefinable code referring me to a website i then performed the koer test and it would NOT complete the diagnostic for whatever reason, i again performed the KOEO test and it gave me a 22 MAP sensor and O out of range. I could not locate the mass air flow sensor, as everything i read the past 2 days pointed me in that direction. I picked up some cleaner to take off the throttle body and TPS and IAC to clean them 2 parts. am doing that now .. i will return with my results from that shortly ... What/ where this MAP sensor i believe the Chilton manual says that the areostar has the MAF sensor but again i could not locate it

My issue. 95 short Aerostar, Vulcan engine, A4LD trans. Just got it last week. Bought a new trans and when I went to pull the van into the shop, it wouldn't start. Cranks but won't run. First thing I checked is fuel pressure, got zero. Pulled the kick panel and found the inertia switch, but the harness for the switch is getting 1.8 volts with the key in "ON" and the same with it in "START". IIRC it should be zero in RUN after a second or two (if the engine isn't actually running, that is), and 14 in START.
Checked all fuses in the panel by the steering column, they're good, and switched around the 3 relays by the battery. No good and I don't hear the FP relay when I turn the key. For now I'll run wires directly from the battery to the pump, just til I get the trans done, but it needs to be fixed anyway because I plan to make this van a DD. Here are my questions:
-Is there a second fuse panel I didn't find?
-Could this be a computer issue? If it is, would the computer fuse be blown?

I have a '95 Ford Ranger, 208,000 miles, manual transmission. It's always run well but about four weeks ago I began to have a loss of acceleration. This had gotten so bad now that I can't drive it. I can't make it up the smallest hill; and top speed is about 30 mph. I've taken it to the Ford service center here, and they say it's because my power steering pump is going bad and has to be replaced. Sounds odd to me; but what do I know! The repair is about 450.00.

Truck = 2011 F250 150,000 miles, no modifications, stock.
Truck lost power yesterday, no boost, and no codes. When driving on Friday, I started moving from a red light. The truck seemed very sluggish. Then I noticed it downshift going up a small hill that it never downshifts before. I looked, and noticed the turbo gauge at 0, no boost. I pulled over, turned it off, then restarted it, but still no boost, and the truck is very under-powered. I looked over the area, and do not notice any leaks, also no leaks underneath. I hooked up my OBD reader, and no codes., the boost gauge is on zero, and the truck has lost significant power. I no longer hear the turbo spooling.
I have spent the past several hours searching sites and forums (Started with FTE ), and it seems that most believe a restart of the truck has solved it for them. However, this is not the case for me, a restart, even after letting it sit overnight did not resolve the issue.
I did see one reference that replacing a NOX sensor solved their problem. This brings up some interesting truck history. Back in June 2017, my truck threw the following codes, P207F and P20EE.
P207F - Reductant Quality Performance
P20EE - SCR NOx Catalyst Efficiency Below Threshold (Bank 1)
The message said I have 200 miles until reduced power. Since it was a Friday, not much I could do at the time so I let it sit overnight, and then the next morning the message was gone. I plugged in the OBD reader and cleared the only remaining code (P20EE), and its been a very happy truck until yesterday.
So my question, can a bad NOX sensor cause the issue of loss of turbo boost, with no codes? Is there another possible cause?

Well, coming home from work Friday and my truck turned on the check engine light. I did not notice any loss of power or other driveability issues. When I got home I pulled the DTC's. I got P0264, P0273, P0276, P0279, P0611, and U0306. The first four being low voltages. The Second FICM. And the last cylinder 6 misfire.
I sent a message to Ed at FICM Repair asking if there was anything to check before I pulled the beast. He said no it needed service no matter what at this point. BUT, I needed to test batteries and alternator. So I spent some time today pulling off my FICM.
I went ahead and pulled the EBP sensor and tube off from the exhaust manifold. The manifold end was very clean. BUT, the sensor end had a noticeable restriction. I would guess a 40% restriction. I cleaned the tube and the sensor and put it back on.
Next I moved to the EGR. I pulled it off and it was dirty but not what I would call restricted. The valve moved freely. I cleaned it anyway and blew out the manifold before I reinstalled it.
I have the batteries on a charger right now. Once they each charge for 12 hours each I will let them sit a day or two before I load test them. They are about four years old, AC Delco 60 month 875CCA batteries. I have had problems the last 6-8 months with staring the truck. If she sits for more than 3-4 weeks without being run she turns over slow and won't start. So I have had to jump start her a few times. And before you ask I have done a parasitic check and only have .05amp draw. So maybe the alternator is getting weak.
On that note I pulled the alternator and will get it bench tested this week. While I was there I noticed the top grooved and smooth idler pullies were a little "wobbly" so I yanked them too and will replace. Might as well do the belt while I'm at it. Boy this is going to get expensive real fast.
So, I decided to go ahead and replace the bottom coolant recovery hose and the long hose/pipe heater hose too. Boy it never ends. Oh well. I would rather do it now while I have stuff pulled off and it is easier to get to. Ordered those parts from RockAuto to the tune of 219 dollars. OUCH!!!
I accidentally broke my new engine oil dipstick while I was trying to get to the FICM!!!! CRAP!!!! More money. So......... Is there anything else I might want to look at while I am there?
The truck is 2006 F250 6.0 PSD CC SB 4x4 mid optioned XLT with 108,000+ miles. I have a 4" turbo back exhaust, AFE Cold Air Intake, Blue Spring, Hypertec Power Program 3 on the lowest setting, and an after market intake elbow at the intake manifold and an engine oil bypass filter. Turbo was pulled and de-coked about 18,000 miles back. Otherwise no issues. The 90,000 mile service was done about 10,000 miles ago. She gets regular services.
How about methanol injection? Will that keep the intake clean from the EGR sludge? I'm not thinking about added power, just keeping things cleaner? I plan to do the Atlas 40 when the FICM gets repaired.

2004 F250 Powerstroke Diesel 6.0L ... 90,xxx miles
Symptoms : Within the past 10,000 miles the truck has begun exhibiting the following problems, sometimes in conjunction with one another and sometimes just independently of one another:Stalling on the road at low speed / low engine RPM.
Throttle pedal becomes completely unresponsive. Stabbing the throttle pedal repeatedly sometimes causes it to return to operation. Sometimes the engine must be shut off and re-started to return throttle pedal to operation.
Rough, surging, stumbling idle at rest. Will crank but not fire occasionally. Problem has become worse as of late. Repeated attempts at starting the engine usually result in success after much, much retrying.
Work Done : Local Ford Diesel technician replaced the EBP sensor, replaced the EGR valve and re-flashed computer with latest software -- all under warranty. Problems still persist.
Peculiarities : We have tried driving the truck with the EGR valve disconnected and with it connected, both at the technician's request.
With the EGR valve disconnected the truck usually starts fine but still stalls out at low RPM / low speed. Fuel economy is also cut by nearly 50% with the EGR valve disconnected. Really couldn't afford to keep driving the truck like this.
Technician speculated that if the truck continued to die with the EGR valve unplugged, it meant that the computer or fuel pump might be bad. ????
It also seems that the stalling problem manifests after the truck has been driven at highway speeds (65-70mph) for at least a period of 20-30 minutes. Stalling usually happens as soon as we make an exit off of the highway and begin to slow down to make exit. As in foot off the throttle pedal. Engine RPM drops then stumbles then stalls.
I wonder if this is a problem with the HPOP or ICP system.
Specifically I wonder if this is a cracked quick release fitting that allows oil pressure to fall after the engine heats up and oil viscosity thins out with the heat. Once the engine cools down sufficiently to thicken the oil, the HPOP finally gets enough oil pressure to allow the engine to fire up again.

Here is this wonderful 5.4 's issue now, sometimes it will idle rough, sometimes it wont. sometimes it feels like it wants to stall, other times not. if im driving about 30mph up a hill around 1700 rpm, the engine feels like a bucking horse, it will kinda want to produce the power, but cant seem to find it till the trans drops to a lower gear. With this engine power loss is unacceptable because it came out of the factory with no power, i cant afford to loose more.
there is no check engine light. its been doing this on and off for a week. i dont drive it much, may 15 miles a day. i thought maybe it was bad gas , i had it sitting for a month, but since then ran almost 2 tanks of gas through it. Seems to act the worst when driving it, then letting it idle for 5 mins, then drive it again, that's when its very noticeable. no smoke from exhaust, no mixing of oil and anti freeze, plugs are a year old, filter is new.

I am perfectly capable of doing the repairs just short on time. the only shop in town is booked out 2 weeks, i need my truck sooner. 2006 f150 5.4v 3v 168k. I bought it with 150k and it was clean and ford maintained from the original owner. for a while it has been fluttering from time to time during acceleration. last week it started shuttering and missing around 45 trying to accel. no cel. I've read and actually fixed my freinds 08 but replacing cop and plugs. I bought motorcraft plugs and granatelli coils. friday morning it didn't want to start, cranked for a bit then locked up, as if hydrolocked.
I let it sit 5 minutes then cranked again and it fired but hesitating and missing like never before. anything passed 3k rpm it ran good no load. i had to drive it and it doesnt want to shift properly, revving way past normal shift points. smoking alot more than normal. hard to tell being 5 degrees out. finally got some codes. bank 2 sensor 1 stuck rich 4 times lean twice. Saturday i changed the oil plugs. and coils plugs were not original but were worn enough to visually see. all of the passenger plugs were a nice brown color. all of the driver side were jet black of carbon which follows the o2 cel. i reset it with my glorifed code buddy and it took a while if at all to come back. so im thinking not an o2 sensor????
It runs rough and will stall from time to time, I am to the point where i wont drive it. i will be replacing the camshaft sensors and vct solenoids tonight, and that one 2 if i have time. from what I've read phazers will cause a rough idle but once under load at least have some performance. when i accel it the rpms stall out before a shift i cant get anymore power, say wont got over 3200rpm. when chains and guides need to be replaced whats the symptoms??

Well my problem isn't a new one. My bonny - will stall at about anytime and anywhere - and yes various power ckts will also fail at the same time. I have cleaned every power connection that I can find. Several threads here have listed answers to this problem - One guy rebuilt his starter - another person found the problem in some wiring on the drivers side of the car in some shorted wiring. Some ignition modules and or coils have been replaced (do these drop out the power rail when they fail????) Interestingly enough I did not find any threads that indicated that cleaning power connections fixed the problem - Also, no one indicated that replacing their alternator fixed the problem. One guy did replace a battery with a leaky cell - he also replaced a neutral safety switch. I don't know which of those actions actually solved his problem. Since so many people have had a stalling problem and a power accessory problem at the same time (especially on 1994 and 95 models)- I thought it would be a good place to start a sort of clearinghouse where a collection of potential repairs could be cataloged. So if you have had a stalling and power accessory problem at the same time.

Recently my old workhorse started coughing and stalling. This isn't consistent at all. I'll be driving and the car will lose power and come back to life. It also stalls at stop signs. Brought to my mechanic and left it for a week with him and he can't figure it out. 1988 Volvo 240 over 200,000....

E99 Romps on start up and randomly dying. Bought this truck about 3 weeks ago. Previous owner mentioned he had issues with it getting hot and shutting off and not starting. Has new IPR, ICP and pigtail, I just put in a new fuel filter. Has 206k miles on it and is the 4R100.
The past two days after sitting all night I have been cycling the key twice and it hasn't done its romp. Typically when it does I can tap the pedal once and it goes away. This I could deal with but its started to die randomly while driving, never while cruising down the road. Its either just after starting it and rolling slowly or slowing down for a stop or to turn. When it dies, I can put it in neutral and it fires back up no problem. SES light usually comes on for about 10-15 seconds after but goes away.
Replaced the grey CPS that was in it with a dark grey one from RiffRaff Diesel. Got a Edge CTS2 to figure out the problem, the codes Im getting are P1280 and P1247.
The ICP pigtail they replaced they spliced on with butt connectors. I plan on pulling it to check for oil and make sure it does look new and redo the connections with solder then shrink wrap them.
I was told to check the IPR% under full throttle which I did and it never went higher than 36.7
The truck did start running rough around 45-50 mph and I did get a video of the ICP jumping around while cruising down the road.
Then I went through a drive through and the truck kind of hiccuped like it wanted to stall and the ICP went right to 725 PSI and idled up and stayed there until I started to leave.
Truck is pretty much stock, K&N air intake and muffler cut out and straight piped.
Here is a link to the videos I got :
e99 7.3 ICP fluctuation while driving - YouTube
e99 ICP steady at 725 PSI after acting like it wanted to stall. - YouTube

SAAB 2007 9-3 - Recently my car has been having a rough idle and stalling on start up. It has been getting worse and I need it fixed ASAP for a long trip coming up. I cannot have this thing die on me while I'm 300 miles from home....
At stop lights the car will have a rough idle while in park and reverse. While in neutral, nothing. As soon as I accelerate, it goes away but does have a lack of power if I really push the pedal. Once I am in 3rd/4th gear, the car feels normal with no issues. If I am on the highway and slow down then need to accelerate, it goes back to losing power BUT if I change over to manual and downshift, car gains power and goes back to normal.
Here's what I have done so far:
1. Changed the spark plugs twice. Once with cheap ones, the second time with expensive ones. I also swapped out the boots.
2. Cleaned the MAP sensor
3. Cleaned intake sensor
4. Replaced air filter
5. Changed oil
6 New battery
The engines gives no codes whatsoever and I have taken it to a couple places and their readers don't see any codes. My SAAB has a built in fuel filter and this cannot be replaced unless you replaced the whole pump (to my understanding). I plan on buying some Seafoam today and see if that works. Also, I have been told to clean my air intake valve but I cannot get the damn tube off! I feel that if I yank and pull on it, it's going to damage the tube. I am not seeing any obvious leaks anywhere. One thing that is weird about my car, since I have bought it used a few years ago, my headlights/tail lights/blinkers go bad QUICKLY!

Almost two weeks ago, I began to have a problem with my car. (2001 Elantra) At times it acted like it was about to stall as I was driving up the smallest incline. Once I got up the incline, my car would jump gears. (second to third, so on)...
The car was taken to Advanced Auto where I received codes about the catalytic converter and the output sensor. I've known about the converter since I bought the car last year and the sensor was replaced. But I am still having problems with the car. My friend is literally having to drive it like it was a stick.
We fear it might be the transmission as I you can go in reverse with no problem. What it could be instead of the transmission?

I am the original owner of the car, which has approximately 125k miles on it. The car has given me great service, but lately a strange problem arose that has my mechanic stumped. When I try to accelerate, the car typically does not respond. After 5 seconds or so, the engine suddenly comes to life and the car begins to accelerate. At high speeds it is not an issue, but the engine sputters once in a while. It has never stalled. It is not the transmission because the RPM stays low during low-power times.
The mechanic initially thought that it was a dirty fuel filter. But, changing it has not worked. Once the engine light came on, and the code was for the air-flow sensor. But, the mechanic is not convinced about that.
The problem tends to become worse after driving for a while, after the engine has warmed up.

I have a 1995 Camry with the 4cyl 5sfe engine and a manual transmission with about 120K miles. It's been very reliable overall, but lately it's been exhibiting some strange intermittent behavior. When driving at a steady speed between 2-3K rpms, it'll sometimes experience a momentary power loss. There's no stalling, but it's as if I've hit a stiff headwind or the brakes have been applied and then release. It doesn't seem to happen when accelerating, but as mentioned above, it's most noticeable when maintaining a steady speed. Sometimes it'll be very quick like it's bucking and other times it'll last a full second or two. It'll do it in all gears at both relatively low speeds and highway speeds, so there's no pattern there. There is no check engine light when this happens, but I have not yet attempted to check codes just in case it might be storing any. It'll happen when the engine is both cold and at normal operating temperature. I've also tried to observe whether or not the tachometer drops when it bumps, but haven't really been able to discern that due to the usual momentary nature of the power loss.
The coil on this car is integrated into the distributor and I read somewhere that it's common for these to start to go as these Camrys age and accumulate a lot of miles. I also read that it's common for these cars to hesitate due to internally leaking fuel pulsation dampeners. The AC compressor makes a little noise, and sometimes it almost feels like what you would expect it to feel when the compressor kicks on, although the jolt or 1-2 second sustained power loss, depending on what occurs, feels stronger than that. Plus it'll do it with the AC off, so that doesn't seem to be a possibility. Other than this problem, the car has no issues whatsoever. It's quiet, uses very little oil, idles perfectly and maintains optimal operating temperature. The miles are about 75% highway since I've been using it mostly as an airport commuter car. Most essential maintenance items, such as the clutch, timing belt, water pump, oil seals, PCV valve, thermostat, radiator, motor mounts, etc. have been replaced within the last 15K miles, and most are Toyota OEM parts. Plugs, wires, cap and rotor have all been replaced within the last 10K miles, again with Denso plugs and wires, but aftermarket cap and rotor. I did feel up under the distributor and got some fresh oil on my fingers, so the o-ring might be leaking a bit. However, I don't know yet if there is any internal leakage inside the distributor itself.
I'm going to tear into it a bit, but I wanted to see which direction to look first. Would you suspect a spark issue (again, no CEL illuminates), or something more like a fuel delivery issue? I also wondered if it might be something like the TPS or perhaps a cam or crank position sensor on the way out.

My 1992 240 wagon (injection) is intermittently stalling, and missing. The lambda light is on the dash. Last year it was doing something similar, but not as bad, and I took it to Volvo and they cleaned the throttle body and said it should be ok, and it was for a while, but now it's worse. Ignition parts are mostly new, I doubt it's that. When it stalls it nearly always starts straight away. When it's missing badly but not stalling, pressing the acc peddle does nothing, until it eventually catches on and revs properly.
I also find that when I have a full tank it's not so bad. When the tank was nearly empty it was particularly bad - it's winter and I was suspecting there was condensation in the tank.
Is there a 'backyard' way of getting the error codes? This could be a good start.

I got a problem with my 03 elantra, recently the car had a problem of stalling. I replaced the crank shaft sensor and that fix the problem, but the car always when idle and then press the gas to go feels like it has no power at all then all the sudden all power kicks in it only does that for a second when i press the gas. What I did was to replace the fuel filter that actually was extremely dirty,but no change i guess it could be the fuel pressure regulator.
