Ford - Windstar :: 1998 - Start Running Rough If Throttle Is Slightly Cracked
Jul 7, 2013
From cold, I start the van up, and if I just slightly crack the throttle it will start running rough. I think it goes away under heavier throttle...might just be that the rpms are up I can't feel it anymore, I don't know. It will idle just fine, and after it warms up it also seems fine. Where to look?Also I sometimes hear a very small, high pitched, vacuum leak from under the hood. What are the most common items that go bad, that I should look at first?

I just bought a 2007 6.0 with 239k miles on the truck, it has EGR delete and ARP head studs. When i bought it the owner warned me of injector stiction...
I drove the truck for about a week, changed the oil over to Rotella T6 with archoil, and swapped out the air filter so far. (previously was non synthetic rotella). I drove the truck 2 more times since changing those two items and then i had a no start issue.
Scanguage2 said it was FICM sync.....so i messed with the wire loom, and got it to start twice but it died right away. (it had ficm sync, then it died and went back to 0) So i ordered a CPS pigtail and was going to change it out today.
Today i went out and pushed on the CPS sensor directly, charged both batteries and the truck started rough but kept running after two times (still haven't changed the pig tail)
Now it starts but is still running rough.
Scangauge 2 Running:
IPR : 23.8
ICP : 581
FICM SYC : 1
FMP : 48.5
The only code i'm getting is P0269 which I'm hoping is only injector 3, a bad injector wouldn't cause all this would it?
I'm just trying to figure out what i should look at next.

I have a great running 98 Windstar. It does not overheat. The oil looks like it needs to be changed but it is not Coffee Colored, as the picture. The PCV valve looks clean, and rattles. I replaced the small 2 inch hose at the PCV valve on the back valve cover since it looked weak in the middle and may have been collapsing. I no longer get the big puddles of OIL/WATER on the ground, that I use to. I cleaned the oil/water out of the Intake Hose of the Throttle Body, but I still see some of the mixture underneath the Air Instake hose after a long drive.
I will go by the Ford dealer and buy another PCV valve, and replace the small curved hose going to the top of the engine near the Throttle Body that the other end of the PCV connects. Someone suggested that this could be cracked, and it does have some small cracks in it at the bend.
I have read that the 99-00 had a design problem with the Valve Cover, and it allowed oil to be sucked out and give similar problem. But since this is a 98, I am just looking for pinched hoses, or leaks. Car runs great, and hoping that I can find the reason that oil is being sucked into the air intake.
Do I have it correct that during normal operation, that the moisture and gases are sucked up out of the engine thru the PCV and into the top of the engine. And that the other Valve cover hose is going in the other direction or from the throttle body to the Valve cover?
Just trying to determine if the oil/moisture mixture is coming from the front or rear (PCV) valve cover. Getting no codes on the engine.

I have a 2002 Ford Windstar. Just replaced a TPS, went to town was coming back home, and all of a sudden it started to spit and sputter while in gear. But, in neutral she runs alright. I use mid-grade gas. I put in two cans of Seafoam in the tank. Wrecker operator smelled the exhaust and told me the it was too rich. My question is and this sounds stupid, could the previous owner. Had never replaced the fuel filter or if they did replaced it, that it was installed backwards. I drove it almost 20 miles before it died. I figured that the fuel in the gas line emptied and it refuse to go. And since it only runs good without strain on the engine...

A couple of days ago (Friday, Sept 14th), I noticed my 98 V8 5.0 liter Mountaineer was idling rough. I had the codes pulled and got P1401, P0455 and P0308. I did find a vacuum leak and fixed it (changed the air filter and cleaned the MAF while I was in there). I also replaced all the plugs (based on the P0308 misfire). I cleared the codes after that with a neg battery pull.
I'm still running slightly rough at idle, but not as bad. However, I have found that when I get up to about 45MPH (1500 RPMs) I started to get a worrisome shaking/ vibration. It's difficult to tell where it is coming from. If I let off the gas, or give it more and go up to about 50 mph, the shaking stops. It is only when I'm pressing the pedal in this range (like it is having trouble switching gears, perhaps?). Over the past two days of driving it and testing, I have been to autozone and had the codes checked. Nothing comes up, and no CEL.
I just had a new trans put on about 6 months ago. The only thing that preceded this issue was I got an oil change the day before this started at a place I don't normally go to (unlikely, but since they didn't write the type of oil they used on my window tag, I figured I'd mention it). I've read some suggest it to be a tire issue; but that strokes me as odd, since the shaking only happens when applying gas.

So,I am working on a 2003 F250 6.0 manual trans. all stock. 204,000 miles. I got it not running. Charged the batteries and pulled the 14 codes accumulated by the last people trying to work on it.There were cyl 1,2,5,6,7,8 contrib codes, P0403 and P0405 egr(the egr was unplugged when I got it), P0341 Cam pos., P0500 VSS, P0562 voltage low, P0683 glow plugs, P1378 fuel inj. ctrl., and a P1000. It is on it's second used car lot, no one can fix it and I don't know what they have done.
Cleared the codes, removed, cleaned, replaced the EGR, installed new batteries, and went over the wiring harnesses. I am down to the P1000, an occasional P0405, and random cyl 3, sometimes 2 contrib codes. If I warm it up and clear the codes, I don't get any contrib codes.
I hooked up the Scan Gauge and the ICP is 554-up cranking, starts without any long crank, runs at 644 at an idle, revs up and reads 2404 max. This is sitting in the garage.
The IPR was 14.8 to start off with, running mostly between 29.7 and 38. revving it up. The FMD is steady 48.0. I have run the buzz test both warm and cold- sounds good, no faults found. Have run the KOER and KOEO demand tests, no faults. There is no smoking. I have changed the fuel filters. I have not located an adapter to hook up my fuel pressure gauge.
As it is right now, it starts reasonably well (it's in the 20's here at night). It runs rough until the temp gauge gets to the top of the little thermometer symbol, then it runs better. The turbo sounds like it's operating as expected, nothing weird. Cold it has a rough idle and poor throttle response. Warm it idles well, with an intermittent light "shudder" .
The weirdest thing I find is the fuel pedal, when I rev it up warm, it won't come back to idle right away, takes 10-20 seconds. It also does this shifting. It does not rev up on it's own, and it will stick at any RPM. I did not find a value for TPS on my datastream on my scan tool (Auto Xray Tech scan 7000). When I let off the throttle the IPR and HPOP pressure drop. The truck was hardly driven for the last 7 years (6000 miles).
I have added some Archoil 9100, that smoothed out the warm operation even more, it drives perfectly down the road (300 miles the other day). I sent the FICM (the guys on the other forum insisted my problem sounds like the logic side of the FICM) to Ed, got it back, no change. I took a peek at the IPR, it is shiny and clean, the connector is tight and free of oil.
I removed and inspected the throttle pedal, it's seems clean and operational. It only has the cylinder contrib codes cold, and it is usually only one cylinder, that cylinder changes, first it was 8 a couple of times, then 3, then 2, now 7. Which injector could be bad and there is no smoke.
I guess the biggie here is to get the throttle to stop sticking. It runs better everyday, but the sticking could be dangerous. The rough running cold cold just be this engines normal. The light shudder at idle goes in 3-5 second increments- light shudder-smooth-light shudder-smooth...

98 5.0 last week i was driving around for a few hours and everything was fine. Did some work in the garage for a few hours and had to run to the hardware store. Started the truck up and she ran like crap. Engine shaking like a misfire. First thought plugs and wires. Well by then it was late and Easter was the next day didn't get to it till Monday. Well after the change still crappy running.
So I changed the fuel filter and cleaned the mass air. No change. Checked for spark on the coil packs all have spark. Checked the PCV all good there. Checked for vac leaks none found. During that I noticed a small hole in the EGR tube I repaired that but still running like crap backfiring out the exhaust, engine shaking badly at times. I also changed out the FPR on the fuel rail. No change of course.
As of today I changed the coil packs. Again no change. Only code it throws is a EGR high flow after I fixed the hole but was having problems before that.

I have a 1998 F150 4.6 2wd regular cab with 255,000 miles on it. Lately it has had some problems. The first is that it will run really rough when under a load, meaning when I step on the gas. It runs smooth at idle and at cruise but when I step on the accelerator it bogs way down and almost shuts off. I have changed the spark plugs, spark plug wires, coil packs and fuel filter. Now I'm thinking maybe fuel pump?
The other issue is that when the truck is having to work a little harder (i.e. pulling a trailer or running in the summer with the AC on) it will start to run hot. I have changed the thermostat, flushed the coolant, cleaned out the radiator, etc. and it still does it. Could both of my issues be related to a fuel problem??

I have a 98 sport 4.0 i bought awhile back and its been running rough.. When driving it seems to cut out.. I had it scanned and it has code PO453 which is pressure sensor.. I was told they replaced the fuel pump when i got it.. After driving and i get out i can smell gas on the drivers side.. I replaced the gas cap but no change.. I was just wondering about this code and what i should start with first..

will it hurt my 98' forester to drive it when one cylinder has no compression? They tell me it needs a valve job for 2,500. They already put a mass air flow sensor in, and replaced plugs and wires. Still got the miss, but I need the vehicle.

1998 Nissan Maxima had a check engine light come on and started running very rough. I took it to get a code read and came up with P0320 and P0325. I'm not worried about the 0325 since that's a knock sensor. 0320 is a misfire on cylinder 2.
With the car idling, I pulled the power connector from coil pack 2 to see if it made a difference in the idle - nope. I did the same for the other cylinders, and each responded with a noticeable change in the idle, which was remedied when it was reconnected.
I moved the coil pack from #2 to #4 (swapping them) and the same problem existed - idle was rough and didn't make a difference when I pulled the power on 2, but it did on all other coil packs. So, it seems the coil pack ins't the problem since multiple packs don't seem to make 2 work, but they work on other 4 and 6.
I then pulled the spark plug from cylinder 2, it was very black and looked in bad shape. I replaced it. Still no love.
I then put a spare plug in the coil and was able to see spark as the engine ran, so it seems that the coil pack at 2 is getting juice.
So, I have gas (big odor when the car is running - seems super rich) I have spark. Still running very rough and the 0320 code remains.

The transmission in our '98 Ford Windstar has failed....sometimes. I went to back it out of the garage and the motor would rev, but no movement of the vehicle. I put it in drive and had the same results. When I put it in 2 it would move. Only in 1 or reverse is it dead. I changed the transmission fluid and filter (Fluid did not looked burned) and it ran fine. After a couple of days, same symptoms. After sitting about a week, I started it up and it acted fine. I drove it about a block. When I attempted to start from a stop sign...no movement. I put it in 2 and drove away.

I have a 1998 ford Windstar with a 3.8 V.6 When I turn my lights on and drive it my lights flicker. I have checked all my grounds that I no of and my connections while driving my lights go dim when I let off the gas. but do not flicker any more. when I accelerate they begin to flicker again. I've had the alternator check and all is good. I have no clue.

My 2006 expedition surges very slightly while cruising under very low throttle. Usually most noticeable at 60-65 mph with no headwind.
Took it in and had my mechanic check it out. He confirmed the slight surge and said it felt like the torque converter was locking and unlocking. No codes or pending codes were found related to the power train.
Abs light is on for a bad rear wheel speed sensor. Code for right rear. Checking the sensor showed 3 ohms for right, 5 ohms left ( left is less than a year old on a new wheel bearing.)
Initial thought was the bad sensor is giving bad input confusing the pcm/tcm. But the condition remains with the sensor unplugged.
Driving down the road watching the tach, it does appear that the converter is not staying locked. Condition goes away with more throttle. Motor runs smoothly otherwise with no indications of misfire. Plugs have 50k miles on them, as does the transmission fluid. Fluid is red and smells fine. Never gotten hotter than 210 by the gauge in the pressure port.
Why would it lock/unlock at very low throttle, but lock tight with more throttle? Tps flaking out? Throttle body motor getting twitchy? Can I pull my popup to the hills this weekend?

Well, I've read a lot of threads on this problem! Try to do my own repairs, so I'm learning and not spending a lot of cash at repair shops.I have an 04 6.0 Super Duty Crew. Starting running rough on way home. Pulled over ,then it died.wouldn't start. Had towed home. Replaced ficm circuit board. No start. Replaced Harness,
icp...... ipr Sensors. Still no start. I noticed there is another circuit board inside ficm. Should I have bought the whole ficm unit?

So my wife's 2005 escape currently will not start. It was running rough so we brought it in to the shop to have the codes read. There was a bad MAF sensor code so we brought it home and were gonna replace the part the next day. The next day rolls around and it refuses to start. Swapped out the spark plugs which was much needed, replaced the valve cover gasket, which had also gone bad, and put in a new MAF sensor. It still refuses to start. It will turn over, but never starts. Also, the sound as it turns over doesn't sound right. It's hard to explain what sounds off about it, it almost has a "soft" sound to it. I can try to explain better if needed.

I have 98 windstar, p1538 code, IMRC. I have physically checked both IMRC's and they are functioning as they should. (if they were bad, they would not move at all right?) Assuming they are good, which step in the troubleshooting process I go to now? The van runs perfect, just that darn light! Do I start going for the O2 sensor now? What to next in the chain of troubleshooting?

I was towing a trailer about 600 miles truck was running great, pulled in for fuel and truck was running rough, refueled and was on my way then when going down a hill (Idle) it just quit, had to tow remaining 200 miles.
After reading the forums I replaced the ICR (ICR screen was damaged) Truck now starts but its very loud and missing like crazy. and surges if i give it a little gas. codes 0268, 0281, 2284, 2288 I also replaced the ICP.
should I replace the injectors? what causes this?
