I have a ford f250 with a 5.4l 2v engine and lately it started to shake when it idles. i have changed all the ignition coils and spark plugs, the injector are fine, but i cant seem to pinpoint the problem. the weird thing is that there are no codes. the fuel trim on bank 1 is around -8 and bank 2 is at almost positive 20 and higher.
View 14 RepliesI was driving my 99 f250 superduty and out of no where it sounded like i had blown a tire started to shake for at least 3 or 4 seconds pulled to the side of the road got out and check tires were good, got back on the road with no more problem.
View 1 RepliesI have a 2011 f250 6.2 cclb and it shakes around 70 to 75 mph. Not terribly but enough to annoy the crap out of me. Now I have put new tires on it recently, new Rancho 9900 adjustable shocks, I have it aligned regularly and tires rotated and balanced every 5000 miles or so. I have had two dealerships look at and my local shop and they can't see anything visibly wrong with it.
View 7 RepliesI have a 2004 superduty 250 4x4 with the 6.0. I am having a violent shake in the steering wheel mostly and can feel it in throttle at about 45 to 60 and at 72 there is s growel. Have changed tires, wheels checked all ball joints tie rods wheel bearings ujoints. Don't matter brakes on or off, od on or off nothing changes it. I really don't know what else to check.
View 10 RepliesThis happens very often when driving around, at first it was only if i stepped on the accelerator to quickly or braked to hard, the check engine light comes on and the truck idles. Nothing seems to be wrong except when i step on the accelerator nothing happens, it lasts about 5 seconds then the light goes out and im on my way. it has started happening more and more just at random times now. it seems quicken the down time if i pump the accelerator.
Second, it occasionally feels like the transmission slips. I'll be driving and when I accelerate the rpms will go up, then what feels like the tranny slipping and the rpms go down. there is a distinct rocking motion when this happens, but it works if I turn it off and on again, or if i just step on the gas the next few miles it seems to subside.
The engine was just rebuilt, 7.3L diesel. New bottom end, cam and turbo also new harness for valve covers and injectors, new #8 injector(#8 cylinder lost compression). The engine cranks and idles great. Run it up to 1800rpm - 2200rpm and you get a miss or skip. Almost like the engine turns off and back on very quick, and it makes a clank noise. No codes, reading it with a OTC Genisys 4.0. I also swapped the PCM and IDM with another truck and it still does same thing. Other truck runs fine. Year model 2000 w/ 230,000 miles
View 1 RepliesWhen my truck is parked, I go to the rear tire and shake it back and forth and hear a slight clunking noise from either the tire or rear end. Its like the axle is making the noise?

This is my problem, the truck Idles then revs by itself and throws black smoke.If i leave it on it eventually seems like it floods and shuts off,when i first noticed this it had a loss of power and was having a hard time shifting gears, it would idle fine but when i would try and drive the truck it had no power. I changed the diesel filters and the air filter and the problem persists.
Could this be a bad turbo? Injector?
Here is the video of the problem.. F250 problem. - YouTube..
My 2003 F250 6.0 It started about a month ago and got worse. Let truck idle for 4-5minutes and idle will jump a few hundred rpms. Got worse as it idles and cant figure it out. It eventually died and died once while driving but starred right back up.
View 1 RepliesOn a cold crank the engine idles rough until it warms or the accelerator is pressed down. Also runs rough going up hills or towing. Check engine light is on and is throwing the code for bank 1 to lean and cat performance below threshold. Cats have been tested, good. Fuel trim tested, good. One mechanic said noth8ng is wrong with it well, there is. 2011 f250 6.2 gas...
View 5 RepliesMy 1999 f250 superduty with the 5.4 was sitting in front of my house, and started all by itseft, did not have keys in it either and the doors were locked. I ran out thinking someone was stealing it but nope,? As far as I know it does not have a remote start either,i have owned it for the last two years and it has never happened before. It is a lariant edition also .
View 14 RepliesMy 1999 F250 V10 has started to lose power off and on. It will run fine then when I stop at a light or sign, then when I take off it runs like I pulling something heavy. If I stop again it goes back to normal sometimes. 161000 miles. No check engine light is on. Motor idles perfect and sounds great. I don't know anything about motors...
View 4 RepliesI have a 2001 f250 superduty 7.3L diesel and my air conditioner just randomly started blowing HOT south texas air. I tried to recharge it with refrigerant but the gauge said that it was over charged as soon as I plugged it into the low side port. What is wrong???
View 5 Replies2003 f250 5.4 86000 miles. When I start the truck, "especially after it sits a day or more" it starts to fast "Rushes". Like the gas pedal is all the way to the floor. I have taken it to the Ford dealer and they say they can find nothing wrong. They say all fords start up fast but I know this cannot be right. If I start it and let it run awhile then start it again it starts much slower. It only rushes like that a second or two and slows down. Today I noticed that when it started all the gauges pegged out. The speed indicator went up past 100mph sitting still in park. Then they all dropped down to zero then back to where they should be.
View 3 RepliesI have a 2002 Ford F250 Superduty with a 7.3 diesel. Brakes started sticking on it. I replaced all the calipers cause the boots were starting to crack but not leaking. All four brakes are still sticking. I can drive a little ways and then the brake peddle feels funny and they start dragging all four. I can loosen the bleeder and brake fluid will spray out and release the brakes for awhile.
View 4 RepliesSo out of nowhere, my tranny started over heating. Got up to 210. It usually runs in the 140-150 range. I have the 6.0 cooler, and 7500 miles on the synthetic fluid. My cooler lines to the radiator were ice cold. I crimped my bypass and this seemed to fix it a little (I know this is a no no), I did the flow test before driving it and it passed. It seems to heat up the most at stop lights in gear. It drives fine, no slipping, no chattering. I also dropped the pan, had some stuff on the magnet, replaced the filter too. It doesn't seem to heat up as bad now, goes to about 190. I will install the new bypass tomorrow when it comes in from the ford dealer. Whats causing the heat? BTW truck has a 4" lift with 35's no other mods.
View 4 RepliesI have a 99' f250 I purchased a few months ago. Here's what happened. Today I was driving down the road and it started to surge. I pulled over and shut the truck off. When I went to start it, the motor turned over slow for a sec and then clicked. When I put a jump pack to it, it fired up. I took it home with the jumper still hooked to it and checked voltage. The alternator was throwing 33.4 volts!! I went to the auto parts store and bought a new battery and alternator. Now the battery shows 11.7 volts steady. The alternator still reads 33.4. Also, if I unplug the positive lead while it's running, the truck shuts off. And one more thing. If the key is off and I reconnect the positive lead, I can hear the fuel rail pressurize. What is going on? I hate electrical gremlins.
View 6 RepliesMy v10 has a cold miss when i start it in the morning no matter what the temp. It misses until it gets up to operating temp.then it runs fine all day with a slight miss.
- Changed plugs,
- Changed pcv,
- Changed iacv,
- Cleaned map sensor,
- Changed tube to pcv,
No codes. Its running as if it had a carb and the choke is closed. No smoke, tach. idles between 750 down to about 500, until it warms up then tach. Stays steady.
I am new to being an F250 owner. Just recently purchased a 2000 F250 SD 4x4 with the 5.4 and a 5 speed trans. Got a pretty good deal on it, because I knew some work had to be put into it, and do plan on dropping the trans. Currently, if the truck has been sitting for a little bit, not cool, but not running for a little bit, when I start it, whether it is in gear or in neutral, there is a noise coming from what seems to be the clutch area.
After a couple minutes of driving, this noise goes away and all sounds as it should. A little bit of researching turned up the possibility of the throw out bearing being bad, however, I found other posts online that doubt this. Another symptom that I assume is connected is that if I go to put it in reverse at 0mph from neutral, it grinds.
In order to go into reverse, I have to press in the clutch, put it in first, then put it in reverse, at which point it goes in no problem. I had already planned on replacing the clutch because it seems to me that would be the logical choice as to where the problem originates, so no issue there. But perhaps I'm wrong??
Experiencing a melt down with one of my trucks. One of our trucks is an 06 F250 SD with 80k on a 5.4L and the other day the tow/haul light started to flash. I took it to a buddy's repair shop (who is an experienced Ford tech and tranny guy) any way, it shifted fine until about the last 1/2 mile before I got to his shop, then it started shifting in and out of different gears. He found solenoid "A" pressure solenoid failure and one other solenoid failure, he replaced all 7 solenoids and also found the pigtail from the transmission to the wire harness bad as well and replaced that. I pick it up and get about a mile down the road and the light starts to flash again so I took it back, he ran his scanner and now found something with the coast clutch and through all his testing it told him the coast clutch needs replaced. He removed the trans. and tore it all down and found nothing wrong with anything, in fact he said everything looked in great shape and thinks the pcm failed.
View 12 RepliesDriving to work the other day my transmission shifted down and the transmission light started blinking. It felt like it geared down like it was in 4x4 I was doing about 55 at about 2600 RPMs. This has happened twice now and lasted around 2 minutes then stopped and ran great.
