Ford Aerostar :: 1995 - Loss Of Power - Cylinder Was Dead
Aug 24, 2012
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.

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.

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?

2001 F150 ext cab lariat 4x4. My father passed away last christmas and my mother would like to have his truck running. A little back ground truck has a 4.6 has always lacked power. Ford did a motor job on it at ten thousand miles saying it was assembled wrong at factory. #seven cylinder has been dead for years. This spring the cat plugged up on drivers side. The local mechanic put two new aftermarket cats on it. Worked ok for a day. Then started acting up. Truck seems to only be running on three or four cylinders. It will start right up but won't rev up if you put it in gear it stalls. My uncle was s Ford mechanic for years and means well but is too busy to fix it. She has been waiting since may for him to look at it. He claims the problem is likely the wiring harness for the O2 sensors that runs behind the engine. Does this seem reasonable?

My 2011 6.7 suddenly lost power, started making noise and then stalled out.
After finding out that there are zero 24 hour service companies available in the LA area, I was able to get it towed to the local Ford dealer.the next day they told me it had dropped the #5 cylinder and that they would have to tear into it to find out what happened.
While I realize that any thoughts on the situation would be primarily idle speculation, what would cause this to happen at only 125,000 miles.

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.

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.

My escape struggles to reach 30 mph.. throttle position sensor code when scanned.Replaced the sensor but still barely any power check engine light hasnt come back on.

What the problem is with my 94 Saturn Sl2? It seems to loose power going up hill. Also I have put in a new alternator and battery, because the battery would go dead after driving for a while. ABS light remains on as well. Also have pinging noise coming from below the emergency brake area, after I have driven it for a little while. Even if it sits idling at times, it will drag down the battery or something, because it will kill and go dead. Could there be a short somewhere?

Having 3 new codes coming up. P0306-misfire on cylinder 6, p0158, p2272. Use my truck as a daily driver for work. Driving along before 80km/h is not to bad but can still feel a little loss of power. If i step down on gas the truck has no power and sounds like maybe cat converter is plugged. If truck is pushed to limit she will make it to her 4000 rpm and will change her gears. So i'm just glad its not tranny.

While driving to work this morning driving about 25 MPH and increasing speed gradually in traffic the lane I was traveling came to a sudden stop, I slammed on the brakes, ABS took over and I steered around the stopped lane of traffic with no issue. Here comes the problem, I never stopped rolling and traffic was coming up behind me in the lane that I just went in to and I stepped on the gas pedal and got nothing, truck was running, no lights or warnings just a dead gas pedal. This only lasted maybe 5 seconds and then it went but it was totally dead no matter how hard I stepped on the gas and vehicles were beeping at me from behind me. It finally went (5 seconds seems awful long when cars are approaching fast from behind) and it drove fine from there on. I guess I plan on trying to recreate this issue but thought maybe there is something with these trucks that caused this that I don't know about?

Replaced the spark plugs and wires a couple months ago. Started skipping yesterday throwing the #4 misfire code so I replaced the coil pack, reset the check engine light but it's since came back on and has a rough idle and loss of power. By the way, it's a 97 F150 4.6L 4x4 with 200,000 miles.

I have a 2008 FX2 5.4L F150. Recently it began to lose power on a friend driving it out of town. He got a check engine light then it just progressively became unable to produce power. It ran but he got down to 10 mph before he could get to a firestone. I got it to a local Ford dealer and they say i need a new engine. They gave me codes for cam sensor and timing and #5 and #6 misfire. (344, 345)
No oil in radiator, no water in oil. The crazy thing is it runs like the day i bought it in Park. But once in gear it begins to cough and then eventually shudders and dies. I haven't changed plugs ever. I know... At about 75 miles it began to idle rough at times and in reverse. But once I revved up it went away.
I replaced both cam sensors but no luck. Today i put it on a tow truck to get a second opinion from a local engine shop. I actually backed it down my driveway, and pulled up to the tow truck with no issues. weird...

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.

I have had an intermittent Check Engine Light for a couple of days --- the van started and ran fine, but the CEL would come on after about 15 minutes of driving. It would sometimes go off before I reached my destination, but it was always off the next time I started the van. No sweat.
I went to read the codes this afternoon and now have a problem. I put one end of a jumper wire into the Self Test Input (STI) and then accidentally let the other end of the wire touch the 12V connector of the starter relay (why is that thing unprotected anyway?). I saw a little arc so I know there was some current flowing.
After this, I connected the STI to SIG RTN for reading the Key On Engine Off codes and got no pulses at all. I rechecked the jumper wire but got the same result. I then removed the jumper and started the van --- it ran quite rough and would only stay running by giving it plenty of gas. The CEL was on the whole time. I did this a couple of times just to be sure.
I guess there's nothing more annoying than turning a little problem into a big one... crap.
I couldn't find an electrical circuit diagram showing the STI in my Haynes manual, so I'm not sure what is likely to have been damaged. I assume the engine control module (ECU) has been damaged, but that is just a guess.
Some specific questions:
- where is the ECU?
- Should I spring for a new one (depending on the ID number), or is one from a junk yard just as good?

Ok I got a 1995 toyota corolla 1.8l dx .... So this is my back up car I went out started it up let it set and warm up and took it around the yard to run it a little well it ran fine then all of a sudden it lost all it's power well I finaly got it back to the drive that was only 50ft away took almost 30mins just to get it there. I cut it off let it sit started it back up and still no power well now it won't even start it has new plugs.. Wires.. Cap button.

This van has the A4LD transmission. I know nothing about transmissions, so, when it wouldn't shift from 1st to 2nd, or, 2nd to third, I researched it on here and found a lot of bad reviews. I also found out that it was likely the modulator gone bad, and how to replace it. I replaced it, and although the new one was restricted and the old one wasn't, shifting was back to normal. So, I was thinking, that was easy enough, pretty good for the original tranny which has 297,623 miles on it, and hasn't been serviced since the first 1k!
Well, that lasted about 75 miles. Now it won't go forward or backward. Everything is still in place, no leaks, fluid level is full. I didn't change the fluid or do anything other than change the modulator. (My friend can't afford to service it properly. Now it may need replacing!) I have only seen problems shifting between gears and OD, TC lockup, etc., but, nothing about not moving at all. What might be the problem? Is the tranny history?

I just picked up Aerostar #6 and am in the process of transferring parts etc. Got this one cheap as it was badly abused and has issues. Big problem, the shifter takes a lot of wiggling etc to get out of park. Is the interlock easy to disable? If so how? Or would a good column from my 93 be an easy plug and play proposition?
