Ford - Windstar :: 1998 - Start Running Rough If Throttle Is Slightly Cracked
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?
View 4 RepliesWindstar :: 2002 - Car Running With Blinking Check-engine Light / Code P0306
So I had a serious runability problem back in 2012 with code P0302 (misfire in cylinder 2) and the car was barely running. I changed the spark plugs, which didn't fix the issues. Then changed the coil, which fixed it. URL...But I was a little lazy back in September 2012, the old spark plug wires looked like they were still in great shape, so I left the old wires on. I think they were the original factory wires, they had the numbers of each cylinder printed on the side. Very nice wires!
Fast-forward to the present. Car starts running poorly with a blinking check-engine light. Not good! I check the code and it is P0306, misfire in cylinder 6. So my first thought was: OK, probably time to change the spark plug wires!I changed the spark plug wires. I purchased AutoLite Professional Series wires at Advance Auto Parts, part 97047. URL...Sure enough, the number 6 wire looked like it had a little corrosion inside the end that connects to the spark plug wire. It looked like I was on the right track! Changed the spark plug wires, and ran it. It still sounded like it might be missing on one cylinder. Just a quiet ch-ch-ch-ch-ch-ch at idle. I took it for a test drive. It ran OK at low RPM's, but had no power. When I tested some hard acceleration, sure enough the check engine light came back on. Tested the code and it was P0306 again. Conclusion: not fixed yet.
OK, maybe the spark plug wire was the problem, just the plug got fouled because the wire was bad. I purchased a replacement spark plug for that cylinder only. AutoLite Double Platinum as recommended elsewhere in this forum. Removed the old plug. I'm no expert, but the old plug looked fine to me. Installed the new plug. Tested it again. Still sounded like missing at idle ch-ch-ch-ch-ch. Test drive, OK with low RPM, no power. Tried hard acceleration, got the blinking CEL again. Conclusion: still not fixed - darn it!
Now remember, I just changed the coil back in September 2012. I had replaced it with a coil from AutoZone. The first coil had lasted ten years. So it couldn't be the coil again this soon, right? But... just to be sure, I went ahead and changed the coil again. I called AutoZone and happily it was still under warranty. The previous coil I had purchased came with a 24-month warranty, and I was on month 23 !!! Sweet!AutoZone also told me if I did a warranty replacement of the coil, the new one would come with a lifetime warranty instead.The part number of the coil at AutoZone was part C1312, Duralast Ignition Coil.
Before installing the new coil, I put a little Dielectric grease around the top inside of each connector on the new coil (7 total, six spark plug wires plus the electrical connector). I think this was recommended in my Haynes or Chilton manuals.I am a tall skinny guy with long skinny arms. So I was able to replace the coil without removing the cowl. Last time I had to remove the cowl (to do the intake manifold isolator bolt repair) the cowl had cracked, also some of the clips holding it down broke. So I didn't want to remove the cowl unless necessary. It turns out with my long skinny arms I can lay up over the motor and reach back around both sides of the intake manifold to reach the coil. It is a reach, but it was possible for me to do the job that way.
I removed the three bolts holding the old coil in place. Then I was able to slide the new coil back in there, around the driver's side of the intake manifold. I transferred over the spark plug wires one by one from old to new (as recommended by another poster) so I wouldn't get confused which was which. It worked well to transfer the rear three first. That hold the new coil near the correct location, and gave me more slack to move the old coil further out of the way.Next step was to remove the wire connector from the rear of the coil pack. It didn't want to release. I looked at the old part (from 2012!!!) and there was a little plastic nub back there to lock the connector in place. It looked like there was room to work in a small screwdriver back there to release the lock. So I wiggled a short flat-head screwdriver in back there (with a wide head) and it released. Then I was able to easily remove the connector.
Then I had more slack to move the old coil further out of the way, toward the drivers side and front of the vehicle. And then transferred the last three spark plug wires to the new coil.Then to secure the new coil in place, I carefully installed one bolt by hand, leaving it loose to allow for final adjustments of position. Installed the second and third bolts loosely. Tightened the three bolts finger tight using a short (3") extension and 7mm socket (1/4" drive). Then snugged them very gently using my small 1/4" rachet. The small 1/4" rachet was a perfect fit using the 3" inch extension and the small 7mm socket. Remember you just want the bolts snug, do not over-tighten them.
When I went back to AutoZone to process the warranty return, they had to do some fancy work with their computer to get me the lifetime warranty on the new coil. By default it would just assume the rest of the original coil warranty from 2012 - which was just about to expire. So they made it right for me - but only because I specifically asked about it. By default, the guy had already rung it up their "normal" way, which would not have extended the warranty for me.Another thing that was strange was back in September 2012 when I replaced the original coil, it had worked well for ten years or so! Also, the bottom of it was clearly cracked, so it was easy to see that it had deteriorated and needed to be replaced.
Windstar :: 2002 Sport - Rough Idle / Vibration And Smell Of Gasoline
After all my attempts, I could not fix the rough idle. I have done the gaskets of the gaskets and bolts of the intake manifold (the engine light disappeared), I have changed the bushings of the manifold too (the one one the left side), I have changes the TPS sensor, I have cleaned the MAF sensor...
The rough idle is still there (and getting worse) and there is some smell of gasoline now. I suspect that I have to change sparks and cables, but I wanted to confirm first with you because the whole thing seems complicated as some of the plugs are buried very "conveniently". You could usually feel an ascending vibration while waiting at the traffic light. You can't feel it as much when in neutral, but it is still there.
I have noticed that on the right side of the Intake manifold (under the throttle) there is some sort of greasy substance that always looks wet. I suspect that it is burnt oil, but that think's been there since I bought the car, so I am not sure if it is related in any way.
I haven't changed the oil and air filter since last summer but I doubt that would be an issue. Additionally I realized that I put pure antifreeze when I need to use 50/50. Anyways, those things I will fix this summer anyways. All I want to fix now is the rough idle because these vibrations drive me nuts.
Ford - Explorer :: 2002 4L V6 Is Running Rough
My 2002 Ford Explorer 4L V6 is running rough I found out why I just don't know what the piece is called because I need a replacement. Mine fell off and fell down the engine and melted quite a bit. Also the part number on my piece doesn't work anywhere, that I have typed it in. Mine has a Ford part number of 1L2U-9F764-AC. Also need to know the proper Ford number. I have a picture I found online with an arrow pointing to the piece I need.
View 1 RepliesFord Ranger / B-Series :: 2002 - Running Rough Like Misfiring
My ranger just started running very rough. Like misfiring, but I think it may be the fuel pump. It starts and drives...but it surges then drives normal, as if fuel is being fed, then starved, then force fed etc. My father asked if I had trouble starting it and to be honest in the last 6 months it was a little harder to start on several occasions. On a few occasions it required more cranking. But that was only a few times.
I tried putting in a fuel injector cleaner and 93 octane gas but it is still running even rougher now. I changed out the fuel filter under the rail about a year ago (maybe 8000 miles ago at most). My father thinks the fuel pump is shot and he laughed because his went on his expedition and he said it is inside the fuel tank and there is no way to get at it without dropping the tank. Is that true? 2002 ranger xl 4cyl
Ford - Explorer :: 2002 V8 - Engine Running Rough - Seems Missing?
On my V8 02 XLT Explorer the engine is running rough like it's missing.
I think a coil may have gone bad,,found a LOT of anti-freeze down in the spark plug hole.
Have replaced the intake but now need to fix the roughness.
Is there any easy way to check each coil? Or should I be checing something else?
Ford Excursion :: 2002 - Running Very Rough And ABS Light Continuously Flash
I bought my 2002 Excursion 6.8L about 2yrs ago, no less than a week of having it I started to have all sorts of problems. (insert nagging wife here) the biggest of problems was the darn thing started to run very rough and the ABS light cont to flash, then the truck just died (engine stopped, EXTREMELY scary in a intersection) I replaced the VSS in the rear diff.. acted a little better for a while then..no luck. I called around to every ford dealer in town. I need more break light fluid to there isn't enough grease on my wobbler pin?
So I got the initiative to simplify what I was seeing and hearing. I found that there was an OSS sensor on the tail of the transmission...drove my very intense self up to the dealership and bought myself a new OSS sensor. I got home and replaced it, then I drove my truck under the largest shade tree I could find and replaced all the coils and spark plugs. (Insert bloody knuckles and curse words here) Job Done. I thought to myself if this doesn't fix it then I don't know what to do. (I couldn't sell it)...again the point being...the truck has never ran better, gas mileage has doubled and the true power of the v10 has been restored. I found 4 different types of spark plugs in it and 3 different types of coils...?
Ford F-150 - 1997-2003 :: 2002 V8 Running Rough - Codes PO353 And PO171
2002 F150 5.4 v8,,, I had troubles just over a month ago with a po305 code. i got the truck fixed with 2 new coils n some gaskets. I am having these po353 & po171 codes pop up now. The truck is running rough and I am curious to if its just another coil problem or if their is something I am overlooking or just don't know about?

These are the code that keep spitting out. I have a 2002 f150 5.4L supercrewand it is running rough. I had this problem about 3 months back but i didnot get any codes from the computer i washed my truck a 1/2 day earlier, 2days later it went away. this time it has spit out 4 codes a po306/po307/po300/po316. the po307 and the po300 are gone, but the other two remain and it is still running rough 2days later. i had just washed my truck 30min. before, it started happening, is there water somewhere? My dad (long time mechanic) says use wire dry on the cops and it will go away. I have read other post on misfiring and I am still not sure what to do?
View 10 RepliesFord F-150 - 1997-2003 :: 2002 - Running Rough And Check Engine Light On
My girlfriend has a 2002 F-150 with the 4.6 V8 and I was going to change the spark plugs for her. She said it started running rough and it threw a code and check engine light. She took it for a scan and they told her the number 5 plug was mis-firing. I'm fairly handy and bought a set of the recommended Motorcraft plugs from Rock Auto, AGSF32PM. It also matched the number in the owners manual so I thought I was pretty safe.
Funny thing, when I took the old ones out, they were AGSF22WM's instead. My thinking is they are a colder plug than the supposedly original equipment, but I don't think they've been changed before. They looked well used but the color was good. The truck has about 135K on it.
Long story short, and to get to the question(s), Would there be any reason the factory would have put a different plug in the engine than what is listed? Am I asking for trouble going with a hotter plug than what's been in there (pinging or timing retardation/loss of power)? Am I just overthinking the whole thing and need to put it back together and drive it?
Ford Super Duty (1999-2016) :: 2002 7.3L Running Rough On Cold Start Ups
2002 7.3 running rough.
This is my symptoms : On cold start ups engine runs rough. Idling it knocks worse than normal on the road she runs really rough. If I get on here she smooths out ( but still runs rough a bit) but normal driving at between 1200 -2000 rpm she runs so rough it shakes the whole truck. It will do this until she gets up to operating temp & then it goes away. The more she warms up the better she runs.
Once up to temp she will run perfectly. The colder it is outside the worse it is & the longer it takes for it to go away. I have replaced the valve cover gaskers and new harnesses, new glow plugs. Still same problems. I have AE and one time it gave me a #2 cylinder code. have not been able to repete this code. What to check next.
Ford Super Duty (1999-2016) :: 2002 F250 V10 Rough Idle / Not Running Perfect
I have an 02 f250 V10 with a rough idle (90K Miles). It's not horrible but it's obviously not running perfect. Everything seems ok when I am up and driving, especially at freeway speeds. I recently noticed that if the truck is in park and I run the RPM's to 1500 or 2K and quickly let off the gas it will die. It never throws any codes. So far I have replaced the IAC Valve, fuel filter, O2 Sensors, PCV valve, cleaned the MAF sensor and replaced the air filter. Plugs and boots were replaced 5K miles ago. Fuel trim levels on both banks are running around -3.1 to positive 3.5 based on what the computer is telling me. Also according to the computer the vacuum sits steady around 25 at idle (+ or - .2). I don't have a manual vacuum gauge, just relying on the computer. I've also gone around to every plug and disconnected both the injector wire and the COP wire and they all seem to equally affect the idle as well as the fuel trim levels.

I have an 02 f250 5.4. I just did the intake manifold. I also changed the spark plugs and the valve cover gasket. Following this I drained the oil and filled it with fresh oil.
It started right up but it felt like the engine was really vibrating and running rough. The check engine light than came on. I don't have one of those tools to diagnose it.
What could be wrong?
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Running Rough With Lots Of Gray Smoke
7.3 auto, starts and idles OKAY, drives fine if you have a light foot but trying to go faster than 50mph or more than 2000 rpm and the whole thing has an anxiety attack. Starts sputtering and popping, lots of grey smoke when it runs rough rough, let off the throttle and it MIGHT behave nicely again.
New lift pump, cleaned the pickup tube, fuel bowl fills nice and fast, just had my edge attitude juice tuner removed since it was causing similar issues that went away for the last 2 months, changed my IPR and CPS (had a mechanic test everything when the tuner was taken out, all injectors buzzed good, sensors good)
When this first happened after the initial problem with the tuner was resolved, it did throw the CEL, but I have since been able to get it to come back on, and my buddies OBD2 scanner wasn't even registering my truck when I hooked up... Dare I say PCM is to blame?
Ford Super Duty (1999-2016) :: 2002 F250 V8 Running Rough - Code P1152
My truck has been doing this for a while now but it has progressively gotten worse from about three months ago when I went through some deep water. I don't believe it had to much to do with the water, I just think that the water is what didn't deal the situation and lead to the problem becoming more prevalent. But continuing, yesterday it got down into the high 20's and my engine started acting up (rumbling coughing, surging while at/leaving complete stops) and then it finally through a code for once and I head over to the neighborhood AutoZone expecting to get a lean code (because when the engine is acting up really badly I can unplug the fourth cylinder fuel injector without the engine acting any differently) but instead I received the p1152 (bank two lack of switching (rich)) code....
At this point I believe it is a faulty fuel pressure regulator, but without a good diagnostic obd2 reader or a fuel pressure gauge I'm not sure what to do. I'm currently in college, money is low, and I'm trying to take an accurate shot at the part that needs to be replaced so that I don't have to buy more than one part. Of course AutoZone says o2 sensor but I changed both about five months ago.. I've been chasing this diagnosis around for way too long now. (It's on a 2002 ford f250 5.4l super duty)
Ford Ranger / B-Series :: 2002 - Started Running Rough / Trying To Stall Out / Black Smoke Coming From Exhaust
2002 Ford Ranger edge 3.0 flex ... Truck was running fine and giving me no issues. I woke for work the other day and went to get coffee and truck wouldnt start. I could hear fuel pump running and knew it wasnt that, it was acting flooded. So today I pulled fuse from fuel pump relay, and got it to start. Put the fuse back in and ran to gas station. On the way to the gas station it started running really rough, very low and rough idle, trying to stall out. I noticed it had black smoke coming from exhaust. I got it home, and got it to start barely, and it has the same very low and rough idle, but my oil gauge was going crazy, flickering back and forth all crazy, and the idol is terribly rough and eventually stalls out. Earlier today I did put new spark plugs in it, but not sure that has anything to do with the issue. I also hooked it up to a computer and it isnt throwing any codes.
View 13 RepliesVenture :: 2002 Running Rough Under Load
I have an 02 Venture WB Package with the 3400 engine. Within the last week is has started to run rough under load. This happens mainly when it is driving, but it does happen at idle when there is an incline or decline.
A little background of what happened. It has not wanted to start all of the time and i heard that it might be a dirty MAF. Well, the MAF is clean and still not wanted to start all or the time. During this time I noticed a plastic line going from the intake tube into the rear valve cover was loose, so I thought this was the problem. I have big hands and couldn't reach the rear vavle cover without rocking the engine forward. When I finally got the bolts out of the mounts that attache to the engine, the engine rocked back a little. I didn't think anything of this and ratchet strapped the engine forward so i could reach the valve cover.
I got the line back in and put the engine back where it is supposed to go and all was well. A few days after doing this my wife told me the van was running rough so i took it for a spin and she was correct. It is hard to describe the sound it makes, but it almost sounds like there is was too much stress on the engine when I have the gas peddle pressed. The van doesn't lose any power i don't think. The van sounds great if it is coasting.
It only does this when there is a load on the engine in drive or if it is idle or parked on an incline or decline. It goes into the shop on thursday the 30th, but I would rather not spend the cash if i can do it myself. I am totally lost with this one. I have a video of the sound when I am driving it, but the sound isn't too loud on the video.
Camry :: 2002 V6 LE 1MZ-FE - Rough Running At All Speeds
I have 144,000 miles on my V6. Just started to notice that the car is surging/hesitating at just about all speeds. It appears to idle fine and if you raise the RPM in neutral I can't detect a problem. If you place the trans in drive, apply the brake and raise the RPM to 1000 to 1500 the engine's RPM varies slightly and regularly, it not steady like all of my other cars. When you are at highway speeds you can feel the car slightly buck, if you take it out of overdrive it is more detectable due to higher RPM. I do not notice the problem when the engine is cold.
I have a hand-held scanner and I see no codes and there is no CEL illuminated. I changed the plugs with OEM plugs at 90,000 miles when I changed the timing belt. Changed the air filter probably 10,000 miles ago. Just cleaned the MAF sensor (after the problem started), no change. Took it to the dealer. They discovered broken motor mounts which I kind of suspected I had, but I didn't feel the symptom were mount related. They said that I was feeling torque converter lock-up. I told them that the range of speeds and gears that the problem presented itself that it was unlikely lock-up.
Alldata suggests that it is a fuel problem and Toyota has some TSB's for drivability. I'm discounting the TSB's because this just started recently. Any hints as to where to try first? EGR, fuel regulator, fuel pulsation damper, injectors, spark plug coil packs, ..... It gets too expensive to just remove and replace the sensors that deal with the fuels system. I have plenty of tools plus a volt-ohm meter and a fuel pressure gauge.
07/21/2009 : While I was at work I added Seafoam to the gas, tank was half full.
On my way home from work I disconnected the EGR Position Sensor connector and the symptoms disappeared and the expected CEL illuminated. When I arrived home I went on Alldata and looked for an EGR system test. I found two, one for the position sensor and one for the EGR temperature sensor.
I had to run out to Sears to pickup a vacuum pump. I performed the tests below up to the point that I needed the pump. I also removed, inspected and reinstalled the EGR Position Sensor before I left for Sears. I did not notice the symptoms on the trip about 14 miles round trip. I'll see if I still have the problem on my way to work tomorrow.
Performed the on-vehicle inspection as listed on Alldata
EGR Position Sensor resistance: 2.6 ohms, in spec
EGR Position Sensor power: 5.0v, in spec
EGR Position Sensor output with no vacuum applied: 1.0v, in spec
EGR Position Sensor output with 5.1 in Hg vacuum applied: 4.0v, in spec
07/22/2009 : Problem seems to have gone away, no bucking or hesitation. Maybe the connector contacts were dirty on the position sensor. Will update if the symptoms return.
09/07/2009 : Noticed that I am getting 2 miles per gallon more than before I found the problem.
