Ford F-150 - 1997-2003 :: 1998 4.2L V6 - Changed Plug Wires Now Runs Rough At 2000 - 2500 RPMs

My F150 with 175,000 miles on gave me a the ol' P0305 code indicating misfiring in cylinder #5. I changed the plugs and wires using Motorcraft wires and Motorcraft AGS34FM plugs.

Now the truck idles fine, does not give a OBD code but runs rough at 2,000-2,500 rpm. Tried it out on the highway and it started "bucking" a bit. Not sure what to try next.

Ford F-150 - 1997-2003 :: Rough Start Then Dies - Code P0171

97 F150 4.6 Vin 6, 5-Speed Trans, 200,000mi, Rebuilt recently. I was on my way to get my truck smogged, but she threw a code, P0171. I read somewhere to clean the throttle body elbow, which I did (needed to do it anyway). After I had everything put back together, I start her, and it's rough and immediately dies. If I keep the RPM's at about 1.5k for a minute, then let off, the truck will run fine for about 30-45 seconds, then die again. I just replaced my IAC and the problem persists.

Ford F-150 - 1997-2003 :: 2000 XLT - No Start - Two Relays And One Fuse Under The Hood Missing

Have a problem with starting. Truck had an alarm system that I took off. Reconnected the wires back to factory. Installed a new battery-starter cable. Checked and had no radio and no power windows. Found two relays missing and one fuse under the hood missing. Installed new. Tried again and have all accessories but will do nothing when turning key to start. With key on I can jump across solenoid by starter and it will start. Once started it will not allow me to shift out of park. If I shut truck off and turn key to on position I can shift out of park and into neutral and jump across solenoid and it runs. Once I shift back into park it kills the truck and we start all over again. I've traced wires and fuses and can't find anything. 2000 f150 xlt 4x4 5.4l....

Ford F-150 - 1997-2003 :: 2000 4.6L - Missing Only Between 1500 And 2000 RPM

I have a 2000 F150 with 4.6l triton 125k miles. i have a bad miss ONLY between 1500 and 2000 rpm. This will happen in any gear and in neutral, but only between those rpm's. seems to happen more constant in warm weather. This miss is so bad it feels like the transmission is going to fall out. but since it does it in neutral i doubt tranny problems. things I've replaced: fuel filter, tranny fluid and filter, crankshaft pos. camshaft pos, TPI, MAF, spark plugs, Ignition coils ( all 8) cleaned throttle body ( found 1 EGR port clogged completely )..

I had a couple codes but nothing constant. Been working on this for about 1 year. Codes p0320 (ignition speed input error) p0262 (injector circuit high cylinder #1). my only question here is...... What would only make this dang engine miss between 1500 and 2000 rpm. motor runs perfect thru all other ranges. idle... high speed.. and even throttling through this bad range is ok.. but when stabilizing between 1500 and 2000 starts jerking and missing like no fuel and no fire. i have put in superchip program couple years ago and it ran fine for about 1 year, then this trouble started... I have put back to stock program but still trouble.

Ford F-150 - 1997-2003 :: 2002 - Runs Rough When Damp Out?

My truck runs rough/bad when it rains or is damp out. It stutters and had no acceleration. I just had a new fuel pump put in January. It improves after a while on the road. If it's wet, my travel sucks.

Ford F-150 - 1997-2003 :: 1999 4X4 - Intermittent Misfire / Runs Rough For About A Minute

I have a 99 F150 Lariat 4x4 with a 5.4, 150,000 mile on it. About 2 weeks ago I blew spark plug out on #2, and a friend who said he has heli-coiled a bunch of these tried to do mine and ruined the head. Anyway, I called a local engine shop and got another PI head, only I used my cam in it. Torqued it as per the book, etc... Mind you that the engine ran perfect before all this.

Got it back together with all new plugs, new exhaust manifold, and 2 new COP's. When I start it-it runs rough for about a min, then straightens back out to run perfect again, and after a few seconds you can hear a solenoid click, then it goes back to missing again. This goes on and on... I went through all the vacuum lines and checked them, checked the egr valve, put on a new IAC, new PVC, cleaned the MAF, and checked everything else with a DVM.

I took it out and drove it.... Runs good for a minute, then it goes back to missing, then back to smooth again. This just keeps going on and on. I noticed when I hear that click, it sounds like a mad rush of air being sucked in, but I cannot locate it. I ordered a new set of COP's to try next. I can understand if it just plain missed all the time, but this it intermittent. Also, the only code I can get is a too lean on bank 1, so I replaced the 90's and the pvc valve. Now no codes but still in and out of missing. It ran perfect before the new head.

Ford F-150 - 1997-2003 :: Idle Rough / Nearly Dies / Surges Above 80 Degrees

'1999 F150, 5.4L, 85K miles ....

Fuel pump failed last year, had it replaced. Ran fine for a week or 2, then one day went into limp-home mode. Mech replace fuel pump relay, again ran fine for a month or so. Now when the ambient temp gets above 80F or so (yeah, it has already this year - I'm in Central TX), engine at full op temp, I'm experiencing some sort of heat-soak issue. Engine runs fine when cold, and at normal op temps on the road, but if it is parked for 15 - 20 minutes then restarted, the idle goes all funky - nearly dies, surges, etc. for a minute or 2, and then it seems ok.

I would go back to the same mech, but he had to close his shop due to health issues, so I'd like to see if I can resolve this. So, it is definitely heat-triggered, and "seems" like a fuel issue, but of course it could be some electrical contact having difficulty above a certain temp.

Ford 7.3L Power Stroke (1999-2003) :: After Start Up Engine Throws Wait To Start Light / Runs Real Rough And Just Shuts Off

My 99 250, 7.3 is having some strange issues as of lately. When I start it in the morning, when the engine has fully cooled down, it starts right up, then it throws the "wait to start light" runs real rough and just shuts off. Run the glow plugs a few times, start it up and it will do the same thing for maximum 30 minutes, then all the sudden I start it and it runs fine. I've replaced the fuel pump, cleaned the fuel bowl, new fuel filter, I just don't know where my problem could be. It doesn't make sense. But once I get it running and it warms up, runs fine all day. Go to bed, wake up, has problems again.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 Idles Fine But Runs Rough After Warms Up A Little

2000 F350. Starts great. Idles fine. After it warms up a little, it will run rough and lose power like it is only hitting on a few cylinders. It will eventually stall unless I push the clutch in and bring it back to idle and then it smooths back out. I figured it was starving for fuel but I can rev it with the clutch in with no issue. I ran it up to 2500 rpm and held it there with the clutch in and ran perfect.

I let the clutch out and start rolling....missing again. The check engine light does come on but my scanner says that there are no codes stored. If I idle it, it will smooth out, and the light goes off. All I have done so far was change the fuel filter which was almost plugged shut and the housing was full of rust looking debris which I cleaned out. BINGO! Nope. Same issue.

I am really at a loss as to where to start. I bought this with 120k on it and it now has 170k and I have not had to do anything other than routine maintenance.

Ford F-150 - 1997-2003 :: 2000 Truck Started Missing And Code P0302 Came Up Along With P0171

I have a 2000 f150 with 5.4 Triton with 165k miles. I did invest in a code reader. It started missing and code P0302 came up along with P0171. Put new coil on #2 and truck ran fine for a few days. Then it started to run rough again. Shaking, Idle rough, no power and CEL came on again. This time code P0171. I changed out fuel filter to no avail. My next step was to start looking for vacuum leaks. As I'm searching, All I am finding is trucks with this problem also get P0174 code. My question is since I am only getting lean on one bank does that pretty much eliminate things like MAF or the famous elbow vacuum leak and make something that only affects one bank like an O2 sensor on CAT more likely?

Ford 6.0L Power Stroke Diesel :: 2003 - Hard To Start And Runs Rough When Cold

My '03 6.0 is hard to start and runs rough when cold. Not just cold outside temps, but engine not up to temp. Starts and runs like a champ once it's up to temp. It was doing this when I got it, but it's getting worse.

From what I've read the common culprits are:

1 - failed solder joints on FICM power supply board
2 - bad power supply side of the FICM
3 - updated flash needed for FICM
4 - injector stiction
5 - leaky O-rings at high pressure oil rail to injectors

I have read up on how to run the voltage test on the FICM with a multimeter.
Seems like I would have to go to a dealer to have the software version for the FICM checked.

I am 100% competent to do the tests and/or repairs myself, but since I recently moved in with my fiance in a condo and my tools are in storage, I will have to do it at a friend's house. That being the case, I want to know what all of the common things are that I may need to check for so I am prepared. So, I wanted to see if there were any other common causes of this issue.

I plan to test the FICM voltage and give FICMRepair.com some business if that's the problem. And if that's not the problem (or maybe even if it is) I will get the injector seal kits and replace all of the injector seals as well as disassembling and cleaning the spool valves in the solenoids. I will also change oil and fuel filters with Motorcraft parts and Rotella synthetic oil while I'm in there.

Stalling - Starting - Buick - Parkavenue :: 1997 - Randomly Runs Rough During Rain / Won't Start The Next Day?

About 2 weeks ago my 1997 Buick Park Ave (115,000 miles) began running bad during a heavy rain storm. It was running fine. Then all of a sudden at a stop light the motor hesitated and wanted to stall. I nursed the gas peddle and limped home and turned the car off. The car hesitated and sputtered all the way home as if I was running out of gas.The next day the car would not start. It turned over but would not start. I tried starting the car for three days. My mechanic friend later diagnosed the car and stated the computer was not functioning correctly. He replaced the computer. The new computer seemed to correct the problem.

The car ran great for the next 2 weeks. Yesterday, it was raining hard while I drove the car about 150 miles without any problem. Then suddenly again the motor started running badly. Again, the motor wanted to stall and hesitate as if I was running out of gas. I limped home again. This morning I tried to start the car without any luck. In addition to installing a new computer, In the last 2 months I have changed all the fuel injectors and installed new spark plugs.I have also changed the fuel pump and repaired the fuel tank. My mechanic say the cam sensor and crank sensor are operating correctly. There is spark coming from the coil packs and to the spark plugs. I do not want to randomly change parts.

Golf IV / Jetta IV :: 2000 - Excessive Blue Smoke And Screeching On Start Up - Runs Rough

I got 2000 tdi with 270000km on it and have a few issues with it and am looking for some information before i start doing some work to it.

First problem excessive blue smoke on start up also runs ruff tell it warms up.

Second the is a screeching noise on start up some times. happens most of the time when the car is cold.

Third sounds like something is dragging or rattling but i have checked and there is i can see.

Fourth when the clutch is in and the brake is on the car runs ruff at idle. i think it has something to do with vacuum used for the brake booster but not sure.

Ford F-150 - 1997-2003 :: 2000 Truck Runs Perfect Then Motor Totally Dead And Starter Will Not Work

Yr 2000 F-150 with V6 . Only 68K miles. 3 weeks ago went into fast food for lunch and then truck would not start. The starter would spin it over real well and plenty of gas etc etc. I came back the next day with a tow truck to take it to the dealer and it cranked and ran perfectly for 3 weeks till yesterday. Same thing. Will not start in parking lot of grocery store.

I only have one key and someone suggested that it could be the chip in the key or the theft system acting up. I only have one key from when I bought the truck 7 years ago used. Someone else said when the anti theft system is screwing up, the motor will be totally dead and starter will not work.

This time I am again planning to tow to the dealer and I fear a huge bill for something that is actually very tiny at fault since the truck runs perfectly well and then mysteriously will not start. This is the 2nd time in 3 weeks I have been stranded. I pulled all the fuses and reinserted. I checked all spark wires and they are in good shape and tight. What could it be that all of a sudden causes the engine to not start up and run intermittently ?

It is something I can do myself and I am pretty capable. I replaced in the last year water pump, power steering pump, ball joints and alternator. So what is not getting..... fuel or spark? The only two things we need for to run ... right ?

Ford F-150 - 1997-2003 :: Runs Rough And Stalls When Stop Or Rolling To A Stop It Would Die

I am having trouble with my 1998 F-150...XLT Triton? I bought the wrong motor for it and installed it, turn out it's a 1999 Windsor 5.4

Problem is that it runs rough and stalls when I stop or rolling to a stop it would die.... It seems ok while cold, but when driven for 20 minutes or more it does it.

I have used original 4.6 harness as well as original spark plug coils and only replaced throttle body, oil filter holder thingy mount, exhaust manifolds are from 4.6.

When the throtle body was on the 4.6 I didn't have when the motor ran. Only misfire due to intake manifold leaking into the 3rd cylinder spark plug.(I thought it was a bad head gasket and changed in....installed the timing chain wrong and messed up the whole motor)

Also I broke a rear brake line and now it only has front brakes and smells like fried transmission oil.. This is my first truck and first truck accidental engine swap. Also the 5.4 Intake manifold is missing 2 coolant sensors and it's giving me the P0118 ECT Sensor Circuit High input...
