Ford Super Duty (1999-2016) :: 2001 F250 Won't Accelerate But Idles Occasionally
Dec 9, 2013
This 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.

I have the gas 5.4l in my 01 F250 Super Duty. I had to change out the leaking Heater hose before I could attack this other issue. The truck starts when it feels like it. I changed the fuel filter and it started fine. Then the next day it wouldn't. Later it would. However each time it does start it dies when throttled up. I am down to thinking it is the fuel pump. My question is, because changing the pump sucks about as bad as changing the heater hose. Can I install an inline fuel pump and deal with the sump pump in the tank later? Are there any Cons to doing this?

My 2001 f250 on occasion will roll a very uncomfortable distance when I put it in park. Not all the time, but enough to concern me. It will roll a good 12-18" before the park rod or what have you engages. Doesn't seem to be affected by grade. Matter if fact it has always done it on just slight grades. Nothing like a boat ramp. It rolls enough that if someone had been front or back it would have bumped them.

2001 F250 5.4 ... I'm losing my mind chasing a Gremlin. I've been having mostly intermittent starting issues with my truck. I've had the truck for a little over a year, after someone totaled my previous one.
It occasionally wouldn't start on the first attempt, but it got really bad in the last couple weeks.
I first thought it was a faulty inertia switch or wiring in that vicinity, as at one point after manually tripping and resetting the cutoff switch it would start, UNTIL I put the trim panel back. At this point I think that may have been a coincidence.
I eventually probed the switch and it tests as it should electrically.
I put in a new fuel filter and things were fine for several days, but it acted up again. That time was last Saturday. Got it to start and all was good until tonight. Now it won't go, and I've tried so many times that I can see the battery power is dropping.
Last Saturday I pulled the relays from behind the radio and cleaned 'em up real nice. Also, just to check another variable I swapped the two that matched.
I'm about ready to change the fuel pump, but I've heard so many people say they did that but the problem was something else. Not only will it costs hundreds of dollars, its cold out and we'll have to drop the tank in the driveway.
In addition to the relay, inertia switch and fuse, I have found some mention of faulty fuel pressure regulators causing issues. I'll pry the vacuum line off in the morning to see if I can detect fuel residue on the vacuum side. (There is some noticeable corrosion on the fuel rail in that area).
I REALLY want to make sure I rule everything else out before spending hours under the truck in freezing weather dropping the tank and changing the sending unit out.
On key-on there is a noise from the gas tank, but someone else listening described it as a click but no whirring.
I do hear the relay clicking behind the radio. (Also, I pulled them again tonight and put a meter to them. With 12V on the primary side, they click and the other side shows continuity on diode check, and about .2 Ohm on resistance mode.)
I went through a lot of trouble to get my spare out looking for the fuel control module before finding out my truck is about 3 years too old to have one too. What else to check?

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.

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

Engine light and error code for tps occasionally comes on , then stays off a while. parts store said it was ok (shows full range) , but ford has an update for computer to fix. engine is v10 and parts store erased code and it hasnt come back. the only indication that something was wrong is the light coming on and once on the interstate at high speed , then the off ramp slow down, the engine seemed to want to stall as if engine not matching actual speed for a few seconds, then it was ok again. I was out of town and the mechanic that looked at it told me to go to Ford for an update. He tested the tps and said it was ok.

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.

I have a new to me 2000 F250 7.3 diesel with automatic. Truck has 185K miles and tranny is starting to slip occasionally. Do these trucks come with a OEM tranny cooler or do I need to add or upgrade the OEM one. Someone also told that there is something called "bulletproofing" the tranny on these trucks. BTW, what would be a reasonable cost to have a two wheel drive auto tranny done on my truck?

I'm having multiple electrical problems and not sure if all related or not but they started at the same time.
1) Occasionally (getting more frequent) truck acts like its almost dead and wont start, but if i remote start it cranks right up
2) Radio doesn't shut off when I open the door, but if i close it and open again it does
3) phone staying connected to bluetooth but its acting up when trying use phone for music
Pretty sure there is more but I cant think of them now.

On 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...

I purchased an 1999 F250 Super Duty truck last Sept., it ran great all winter, now when I accelerate I notice a whining type noise (that's the only way I can describe it) it only does this during acceleration not @ idle, could this be a bad water pump? However there are no leaks or puddles of anything in my driveway.

2011 f250 gas 4x4... I bought last year with 65k miles, now has 105k. sometimes when accelerating it slips for a second like a manual would if you jabbed the clutch while pulling. I had the 100k trans flush done. I noticed it a couple times before but more frequent recently. How concerned should i be?

I have a 1999 ford f250 with a 6.8 liter v 10 engine. At about 40mph the truck will start missing and lacks power to accelerate further. This problem is intermittent. Some days it runs great and others the miss appears. Well I scanned and the code reader said that I had a misfire on cylinder 7. I took a chance and replaced the COP and the boot for that cylinder . Ran great for a day and then the miss came back. Same code again. What else might cause this? Are plugs difficult to change in these engines?

I have a 99 F250 5.4l 4x4 Super Duty that just all of a sudden stopped going over 30mph. I was traveling down the highway at 70mph and all of a sudden the truck acted as if it were in neutral and started revving up. i let off the gas and the problem stopped. i went to pass someone and it occurred again. I slowed down to 65mph and a couple minutes later it did it again. I wasn't too far from home so i drove it there. By the time i got around the corner I had the truck in second gear to prevent me from going over 25mph. i allowed the truck to rest and then checked the transmission fluid and everything looked good. There was a slight squeak that had just started and appeared to be coming from the drive shaft. I am mechanically inclined but new to working on vehicles..

2003 f250 crewcab 6.0 auto 4x4. I all of a sudden started feeling a vibration under the truck near the back when I accelerate and when I let off the gas no other time. No noises or clanking just vibration. I can wiggle the driveshaft inside the carrier bearing do you think that could be it or is it the rear end.

So after this weekend's hurricane my 2011 f-250 started to making a noise when I accelerate. I don't know if water got in some where. But there's no MIL light coming on.

I have a 2011 F250 with the 6.2 gas engine. I have been having a problem that the dealership says there is nothing they can do and have never heard about.
After the truck sits all night I get in and drive it for 10-15 min. It gets warm and I get out turning it off. When I come back about 15-45 min later I start it up and go to leave. As I pull out and start to accelerate in first gear the truck goes to an idle for about 2-3 seconds. I push the gas pedal and get no response. After a couple of seconds it picks up wherever you have the gas pedal. If you have the pedal to the floor it jumps you forward. This is not putting on any lights and the computer is not throwing any codes. According to the dealership the computer is telling them there is nothing wrong.
This has happened 12 times in the past 6 months. It has happened since I bought the truck. I have just started documenting it as of 6 months ago. It is not something I can make it do on command. After it happens once it doesn't seem to do it again for a week or two. I have 31000 miles on the truck. The dealership has had it for 4 days now and can't seem to get it to happen for them.

Just bought my first Ford. Its a 2015 F250 Platinum. Im at 1400 miles and Im becoming concerned because when I start the truck for the first time in the day, no matter how long I let it sit and warm up I am noticing that on the first couple of miles of driving I hear a high revving sound as I accelerate and it seems to quick shift during those first few miles.
As I continue to drive the high rev sound just fades away and all engine sounds and shifting are as normal as can be and will remain that way until the truck has been sitting for an extended period of time and is cold. I thought it had something to do with tranny temp but this morning I let the tranny warm up to about 115 deg in neutral before taking off but still had the high rev for the first few miles. I have never owned a ford nor have I ever owned a heavy duty truck, hoping this is normal.
