Ford F-150 - 1997-2003 :: 2002 - Stumble And Try To Die When Give It Any Gas


Mar 4, 2014

I have a 2002 f150 with a 5.4. It runs bad but all the data looks good. When you rev it in gear it revs sluggishly but when you put it in drive and give it any gas it will stumble and try to die. Un plug the tranny and it revs great and when in gear it runs great, but it obviously is stuck in second gear. I have codes for tcc short, solenoids a and b short, tcc short, and pressure control solenoid. I have replaced all of these parts inside the tranny including the wiring harness and main connector (transmission side). The OD light is also flashing. I Have run out of stuff to replace, obviously its something transmission related if the truck runs fine with it unplugged.

Ford F-150 - 1997-2003 :: 2000 5.4L 4x4 - OD Hard Shift / Slams Into Gear When Give It Little Gas

I have a 2000 F150 5.4l 4x4. When I am going over 50 on the highway and I am in OD, if I let off the gas a couple of seconds later it feels as though the brakes come on because the truck slow down so drastically and when I give it a little gas it slams into gear. It feels as like there is a "gap" where nothing is engaged before it slams back in. This is a rebuilt tranny with less than 7K miles on it. I took it back once and they said it was the motor mounts. I had those replaced and still the same problem. I replaced the spark plugs 6K miles ago and the COPs 3K ago. There is 170K on the truck. I only drive about 8K miles a year.

Ford F-150 - 1997-2003 :: 1999 - Engine Stumble At Load

1999 4.6 (106K miles) will stumble / miss when at 35-50 mph under a mid throttle load (just before reaching the downshift point). Has been doing this since I bought the truck at 70K miles.

Computer has no codes, engine runs fine under all other circumstances, and gets a decent ~20 MPG on the highway.

Done the standard tune up items (plugs / motocraft) and cleaned MAF, replaced TPS, tranny flush/ filter. Replaced the left O2 sensor 2 months ago, but it dumped a code and was really noticeable when it went out.

I am about ready to dive off and replace the MAF, but at $100 a shot would like other alternatives to try first. I am really convinced the engine is leaning out and misfiring under this load.

Ford F-150 - 1997-2003 :: Slight Stumble / Misfire When Under Acceleration

I have a 97 F150 4.6. The truck has developed a slight stumble/misfire when under acceleration. Once at speed it runs fine. It has not given any codes. I've checked for them several times. The plugs and wires have been changed. Is it possible that a coil pack could be bad without throwing a code?

Ford F-150 - 1997-2003 :: Slight Miss / Rough Idle - Hesitation Or Stumble On Acceleration

2003 F150 5.4 72852 miles

I have a Rough Idle & sometimes a hesitation or stumble on acceleration. I cleaned the MAF & IAC motor & Air & Fuel Filters are new. I got a 20890 scanner & ran test 6 53 as suggested in many posts by BlueGrass. Here are My results & what They Convert to.

1 00F5 .3675
2 0051 .1215
3 0000
4 0000
5 00A3 .2445
6 0000
7 0000
8 0000

I'm guessing the cop's are ok & probably need plugs? I was hoping to just swap a coil. Too cold to do plugs & truck won't fit in my garage.

Ford Escape / Hybrid :: 2002 - Stumble At 1k RPM In Park And Neutral

So my buddy has a 2001 escape. It has a shudder at 1k rpm in park and neutral. It's not nearly as noticeable in drive. I scanned it for codes and there isn't one. Ran a power balance on ids and it's straight. Doesn't miss during the shudder either. Has all new coils and plugs. I cleaned IAC. MAF. Ran sea foam through the engine. And there is Lucas oil conditioner in the oil and Lucan fuel injector cleaner in the gas. It runs amazing other than that shudder. What could it be ?

Ford - Focus :: 2003 - Stumble And Hesitation At Steady Speed

I have a really weird issue with my 2003 Ford Focus. Manual transmission, just over 50,000 miles. I've been noticing a stumble or hesitation (like the engine is cutting out) at steady speed, but ONLY when it is snowy out, more if it's windy as well. I don't recall that this happens if it's rainy or foggy. All maintenance is performed as specified, to include air filter changes.

Ford - Aviator :: 2003 - Odd Stumble / Shutter While Driving Down The Road?

I have an '03 Aviator that has this really odd stumble / shutter while driving down the road. It loses power and feels like it is going to stall. This is very intermittent and not obvious at idle. Sometimes on hills, sometimes just cruising along. I did some reading and thought maybe I had an ignition coil(s) going bad.

I took the covers off the coils and pulled them out. Six of them looked perfect with one being newly replaced by Ford. Two of them had a thin film of oil mist on them both outside on the rubber boot and inside the rubber boot. I wiped them off and put them back in. There was no oil down in the plug bores and the valve cover gasket looked good. The plugs looked good too.

Is there any way to actually test these? If the problem is intermittent I am not sure if they would fail a test until they got hot from use. I do not have any lights or codes.

Ford F-150 - 1997-2003 :: 2002 - Cannot Get Transmission Into Gear?

Woke up this morning and was going to work. Went to unlock my truck and noticed the lights didn't come on inside when I used the remote door unlock. Then I started truck and the tranny lever on the steering column wouldn't go into gear plus the sterring wheel will not lock when the truck is off!

Ford F-150 - 1997-2003 :: 2002 - Key Less Entry Won't Working?

2002 F-150 XLT. Came with factory keyless entry. The remote type, not the keypad on the door.

A few months ago I noticed the remote would not unlock or lock the doors when I pressed the remote buttons. Usually after a few tries it would work though. Fast forward to Sunday and now the remote doesn't seem to work at all.

I changed the battery in the remote. No difference. Then I then reprogrammed the remote and it worked fine locking and unlocking the door. So I thought I was in the clear. Then this [Tuesday] morning I try hitting the button on the remote and sure enough it's not doing anything.

I'm really stumped what to do here. Could the receiver in the truck be bad? The truck isn't driven a whole lot. But the battery in the truck has enough juice to start the truck. So I don't think that's the problem. Any guesses?

Ford F-150 - 1997-2003 :: 2002 - Transmission Is Shot

I have a 2002 f150 lariat super crew 4x2 with a 5.4L engine with 145,000 miles. My tranny is shot, and i was told it happened because the tranny cooler went bad. A few people have told me it sounds strange that the cooler went bad on its own. The truck is still at the shop that diagnosed it and i cant seem to figure out if it has the 4R70w or the 4r100 tranny in it. Is this something that's standard or something i will have to look at on the truck itself to figure out.

Ford F-150 - 1997-2003 :: 2002 - Couldn't Program Key Fob?

Bought a 2002 F150. NO door button pad, and the guy lost the FOB. I bought a new FOB, but i cant get the truck to go into program mode. Suppose to turn the key on- off, 8 times and horn beeps... I never get the beep. There is a 5 digit code on the card in the glove box, so i assume it came with remote entry. How to check ? There is also a small black box about 1 inch cube attached to windhield infront of thr mirror. Has a blue LED light on it and small wireharness into roof console area. My 2001 did not have this. Is it factory for compass or part of aftermarket remote start or alarm system ? Would something like that disable my ability to program the FOB ?

Ford F-150 - 1997-2003 :: 2002 - Replaced ECM Now Won't Start

Well...I had the ECM replaced on my 2002 F150. She ran great for about 60 miles. I had trouble with the key right off at the dealer - it wouldn't start, so I flipped the key over, and it started. Drove about 35 miles, and had starting issues a couple of times, but minor, and over quickly. Came home, and did not drive it for a week. Got in this morning, and it WOULD NOT START. Turned over normal, but won't start. Now I am stuck 15 miles from the dealer who programmed it, and no way to get it there. Anything that I can do to get it started to make the trip?

Ford F-150 - 1997-2003 :: 2002 - Transmission Stutters While Going Into OD?

I have a 2002 f150 2wd 4.2l engine. With 135,000 miles I just replaced the battery about 300 miles ago and I usually tow a trailer almost always. Also I replaced the Plugs and Plug wires about 15,000 miles ago When I am towing I turn the OD off. Now the problem. I noticed that when I am not towing now that when approaching highway speeds it seems to shift back and forth from overdrive while accelerating only.

But when pulling a trailer with OD off it shifts fine. No engine codes appear. I am due to service the transmission fluid I think I have about 35,000 on the fluid now but before I do I just want to pass this that while I have the pan out. Is there anything else I should check or could this just be a issue with dirty fluid Or Possibly the drivetrain controller because I hardly ever drive without towing..
