Ford Super Duty (1999-2016) :: No Power When Driving And Accelerate
Jan 23, 2016
So I have a no start on my 6.0. I was driving and went to accelerate and had no power, pulled off of the road and was idling rough, I checked for fuel leaks-none. I put it in drive and engine cut off and wouldn't start again, changed the ICP (threw a code) still nothing, FICM is good, ICP is 950 psi at cranking, IPR is only at 54%. I'm at a loss of what to do next besides looking at the IPR, and I do not have the equipment for a leak test.

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 don't know what is wrong with my truck. I don't know what this symptoms called, but It felt like it was missing a beat. The engine suddenly lost power for a second or two wile driving. It did this few times. Is it the engine or the transmission? No check engine light is on. 2001 F250 5.4 V8

I just picked up a 2012 F350 lariat with about 65 000 miles on it, and while driving home, it popped up with reduced engine power on my screen. Tried adding DEF fluid, seems to right up to the top already, no actual change in engine performance either. Also, no check engine light or service light on (wrench light)....never run across this before and am totally thrown off. Haven't taken to dealer yet...

I have a 2003, f-350, 6.0L with a K&N Filter. While driving the glow plug light comes on and the power is shut down. After a few seconds the power comes back and it won't do it for a while. No codes. I replaced all of the glow plugs and wires. What's causing this?

I have a 2007 6.0 with 260k on it losing gauges and radio intermittently while driving. Lately 2-3 times a day, lasting 3-4 seconds a time.
I have heard it could be the shift lever, instrument cluster, fuses, etc. I have kind of ruled out fuses based on the behavior of the failure.
Looking for a second opinion before I start taking the dash apart or send it in. The truck just can't be down for a long time right now.

I have a 2008 Canadian F250 SD 5.4 triton. Its got 224000km on it and began to get the dreaded 5.4 dieseling when hot and idling. I replaced the timing chains, guides, both tensioners and crank gear. I confirmed the cam timing was correct with the crank key at 6:00 and the chains marks on the R and L. I replaced 2 coils on cyl's 2 and 3. I replaced the MAF sensor, fuel rail pressure sensor, cleaned and confirmed working the crank sensor and both cam sensors. I fixed the broken Bank 2 cam sensor wires. I changed the plugs and replaced all 4 O2 sensors.
Now the truck idles great but when driving it bucks and coughs and has zero power. I cant even get to 80km/hr. The computer now shows codes P0172 and P0174 which means the Bank 1 is rich and the bank 2 is lean. The O2 sensors are working and moving around. The back 02 sensors are both reading in the 0.8Volt range but bouncing around. The front 02 sensors are both moving from 0.1 to 0.8 constantly. The long term fuel trims are +9.5% bank 2 and -4.7% bank 1 at idle. When the throttle is off idle they become +25% bank 2 and -25% bank 1 . How is this possible and what can I do to fix this engine?.

While driving up hill at 60mph the truck lost power. Rpm jumped up as to change gears as it hit 55mph. Still losing power until it shut off. I tried to restart and just got a click from the solenoid. No engine codes whatsoever. Battery had 12.1 volts but when turning the key to start in getting 8 volts. Had it towed home. Today I swapped batteries with my other truck and same click noise from solenoid. All lights, radio, ect still work. Where should I start? Alternator, fuses...?? 2008 f250 5.4 ...

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.

My Superduty recently started clunking when I accelerate from a dead stop. The harder I hit the gas,the harder it clunks. I unbolted the driveshaft from the rear end and the yoke slides easily. Tranny mount looks tight. Could it be the front driveshaft? Sometimes when I brake hard and the truck comes to a complete stop it will do it too.

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 2003 F350 6.0 King Ranch. My first diesel truck. Bought it in March 2016. One owner with 102000 miles on it. Has a Bullet Proof oil cooler and 4 inch exhaust. Truck ran great until a week ago. Now, under any hard acceleration it blows out blue/gray smoke and does not seem to have as much power. Coolant level is constant and I cannot find any traces of water and oil mixing.

I'm looking to buy a 08 f250. It has 70k miles on it. The guy is running a mini max tuner on it. I did notice on a cold start as soon as he hit the acceleration it had alot of black smoke. Is this normal? And is there anything I should b aware of when looking this truck over.

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 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.

2003 f550 with 7.3, suddenly loses power and struggles while driving. White/blue smoke comes from tailpipe, can smell the diesel exhaust bad when happens, comes and goes intermittently but has been happening more and more often. I uploaded a video onto YouTube to show sound, rough running motor and smoke from exhaust although smoke not that bad in video. Search "shadetreelandscaping" on YouTube in case link below doesn't work.

Took to ford dealer a few diff times for problem and they can't get any codes, can't duplicate problem. After it being in for third time they say had to call ford tech hotline and they suggest replacing injector however can not and will not gaurntee that will solve problem, and obviously dealer isn't cheap for repair. I find it hard to believe that a bad injector(s) would be an intermittent problem as it is or that it would cause fuel pump to make gurgling sound.

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.

Ive got a 04 f350 that after u shift into 4hi or 4lo when u accelerate it it makes loud clunk noise in fwd or reverse hi or lo. With hubs unlocked it still clunks. Have checked, wheel bearings, axle U-joints, and driveshaft joints all good. So I am thinking I've got issues in t-case. Popped drain plug out and wow that dex merc 4 looks nasty. So thinking I need exploded view of transfer case.
