Ford 6.0L Power Stroke Diesel :: 2005 F250 - Engine Cuts Out For A Split Second When Releasing Throttle
Oct 10, 2015
This truck isn't mine but it's an 05 F250 automatic. We just did oil cooler, STC, standpipes, dummy plugs, EGR delete, and cleaned the turbo. Truck starts perfectly and runs great 99% of the time. But after a high load throttle situation right when you let off the throttle the engine sounds and feels like it cuts out for a split second, then it comes back and everything is fine. It does it with stock tunes but it is more noticeable with his SCT tunes loaded. There are no codes being set. The weird thing is if your drive it relatively easily it never does it, and it never does it while it is actually under high load, at WOT it pulls like crazy until you let off a bit and then it happens.. It also doesn't do it every time but it is fairly often. It has edge insight with fuel pressure monitoring added, ICP doesn't drop out and neither does fuel pressure. What could cause it to do that?

I just purchased a used f250 6.0L a week after having it i noticed a small oil leak slowly got worse (looked as if it was coming from the too rear of the engine) then noticed about a half quart of oil under my truck. While driving it home the oil pressure gauge kept dropping then going back to normal then eventually dropping for good. The truck still ran so i drove it to take it to the mechanic but then the throttle began to become unresponsive and then gain power again then finally the truck shut off and wouldn't start again, blowing oil all over the inside of the hood and top of the engine. I checked it and noticed the pressure sensor pigtail were fraid so i replaced that along with the sensor and added oil but still wont start.

I'm TSing a no-start on my 2005 6.0L F250. Engine cranks fine. I've been working my way thru the TSing guide and using my new ScanGaugeII. No codes found. At glow plug warmup, (dash light goes off), I'm getting 40.5v FMP, 11.0v FLP, 14.8% ICP, and 0psi IPR. After cranking for 10-15 sec, get 35.5v, 10.0v, 84.7%, and 446psi. I've had a trickle charger on all night to keep the batteries charged. Have not seen FMP over 45 or IPR over 470.

Last week my battery light came on for the first time in years. I have a 185 amp DC Power alternator after dealing with so many bad oem ones.
Anyways, battery light came on when i pulled up to a stop sign. I proceeded to plug my sct x4 in to see what the voltage was, with the battery light it was 11.50. I shut the truck off started it back up, no light and voltage was 13.7. Went through the stop sign got into some more traffic, started to accelerate again and this is when the truck shuts off for the first time. Put it in neutral, and it started right back up.
Several days later it shut off on me two times back to back. It was a cold start, and both times the battery light was on and the truck would die within 30 seconds. Third start it kept running fine.
This past Saturday morning battery light was on, let it idle for awhile then as i tried to park it in the garage it shut off. Started it up, no light so it ran fine. Later when i started the truck it shut off again. So it has shut off on me 5 times in the last week.
Some more background on the truck:
2005, 199k miles
Well maintained (T6 every 5k, filters every 15k, etc.)
The injectors are going bad, it started running rough saturday 1/9/16, just a couple days before it started shutting off.
I used to a sct x4 to pull codes, i have p2237 (if i remember right) which is an intermittent icp signal. I replaced the pigtail and icp less than a year ago because of the same code.
And three codes for glow plug solenoid open on 5, 6, and 7.
No ipr codes

So, we have a 2005 ford F 250 6.0 diesel and we had the engine changed out from a 2006. Now the truck will not start on hot crank. It will start up normal when cold. So dummy plugs and stand pipes were changed out as well as the oil pump and turbo from the 2005 engine because they were still perfect. What else could be causing the truck not to start up after truck is hot. Does the engine number have anything to do with it? Or anything electrical

My truck has been doing great lately after the major surgery she's been through. She is an '06 F-250, with about 238k miles. I've noticed a few days ago that there is a grinding noise and feeling in the gas pedal. (Or diesel pedal..? ) I can feel it right when I slightly ease into the throttle. It goes away once I'm up and going. But its the kind of grinding that sort of worries me. It is also apparent when in reverse, almost more noticeable.

2005 6.0L F250 Lariat. I picked up a couple weeks ago. The message center in the gauge cluster will only show my mileage (kilometres) and engine hours but nothing else.
Also the three buttons/controls to the right of the steering column don't do anything. I checked the wiring behind the dash and it's all plugged in... The other problem is the SRS light will flash on and off while driving.

2003 f250 6.0.... recently did oil cooler,hpop,ipr,icp,fuel pump,egr valve, rebuilt the turbo.... when around 35mph truck seems sluggish and doesnt seem to pick up quick untill i floor it an then hauls butt.. vgt reading at idle is 62% and when floored around 30 to 35%.. fuel pressure is 63psi.. ipr is around 60 to 70% when floored and around 25% at idle. Hpop reading when floored is 3000 to 4000psi and idle is 624psi....

I've been having rather slow throttle response with my 6.0 f250 diesel at lower RPMs. Obviously, this is to be expected to some point.. Whether I'm cruising on the highway or through the neighborhood, if the truck is at lower RPMs and I try to accelerate, it doesn't want to. In order to get it to accelerate, I have to press the gas down enough to downshift it then it'll take off.
The truck doesn't have a loss of power at higher RPMs, it takes off like a bat out of hell. I've put 175CC injectors in, tuned it, power max turbo, EGR deleted / studded, etc. It's almost go out with acceleration, or go turtle power with acceleration.
Oil pump was replaced a couple years ago. This problem existed through it all, and it's rather annoying. The truck doesn't want to produce any low end power. If I try to hit the gas enough to accelerate but not enough to force a downshift, I'll just blow smoke, spool the turbo, and barely accelerate until I down shift or push the truck through it. Turbo PSI is roughly ~15ish-20ish during the sluggish transition.

So I was driving to work and the truck lost throttle response. There was very little of it! Came to a stop then it didn't barely want to move, pulled over then it died on me! No clue what to look at! 2005 6.0 232k miles

2004 F250 Powerstroke Diesel 6.0L ... 90,xxx miles
Symptoms : Within the past 10,000 miles the truck has begun exhibiting the following problems, sometimes in conjunction with one another and sometimes just independently of one another:Stalling on the road at low speed / low engine RPM.
Throttle pedal becomes completely unresponsive. Stabbing the throttle pedal repeatedly sometimes causes it to return to operation. Sometimes the engine must be shut off and re-started to return throttle pedal to operation.
Rough, surging, stumbling idle at rest. Will crank but not fire occasionally. Problem has become worse as of late. Repeated attempts at starting the engine usually result in success after much, much retrying.
Work Done : Local Ford Diesel technician replaced the EBP sensor, replaced the EGR valve and re-flashed computer with latest software -- all under warranty. Problems still persist.
Peculiarities : We have tried driving the truck with the EGR valve disconnected and with it connected, both at the technician's request.
With the EGR valve disconnected the truck usually starts fine but still stalls out at low RPM / low speed. Fuel economy is also cut by nearly 50% with the EGR valve disconnected. Really couldn't afford to keep driving the truck like this.
Technician speculated that if the truck continued to die with the EGR valve unplugged, it meant that the computer or fuel pump might be bad. ????
It also seems that the stalling problem manifests after the truck has been driven at highway speeds (65-70mph) for at least a period of 20-30 minutes. Stalling usually happens as soon as we make an exit off of the highway and begin to slow down to make exit. As in foot off the throttle pedal. Engine RPM drops then stumbles then stalls.
I wonder if this is a problem with the HPOP or ICP system.
Specifically I wonder if this is a cracked quick release fitting that allows oil pressure to fall after the engine heats up and oil viscosity thins out with the heat. Once the engine cools down sufficiently to thicken the oil, the HPOP finally gets enough oil pressure to allow the engine to fire up again.

I'm having an issue with the truck not staying idle after cold start up. The truck will turn over and start right away (not even 2 second crank) but immediately dies. The throttle will not work at low RPM. When I start the truck, it will instantly rev high, the revs will drop low, it will try to compensate and rev high again, then it will immediately die.
If the RPMs are under under 2.5k, the truck will immediately stall and die. When I attempt to use the throttle under that RPM, it will not work. No matter how much I depress it, the engine will instantly cut and stall out. It will not attempt to deliver fuel. The only way I can get the truck started is if I rev the engine high and hold it. I need to hold the truck at 2.5k+ RPM for atleast 30 seconds. It generally takes me about 5 tries to finally get it running (mainly due to the throttle immediately cutting out and I have to 'catch' and hold it.) After that, there is no sign or issue. The truck will start immediately back up after it's been running for a couple minutes.
CEL: MAP sensor (0069?) -- Sensor is spotless. Harness looks fine. I replaced the injectors, both batteries, and the alternator this summer. It doesn't sound to be any these either as the truck sounds extremely healthy and immediately turns over.

2011 6.7 with 3.55 gearing. Just got the truck. And it seems when its cold the truck will rev high in 3rd gear and then sort of fall into 4th gear sort of losing power for a split second. If I gas it hard, its not as bad. Usually only happens like I said when its cold. Check the trans fluid its full and looks clean. My guess is some sort of sensor or the computer???

I have a 2005 Focus 2.0 ZX5 manual. 131,000 miles. I believe this has been an ongoing intermittent issue until now. Occasionally while driving before at 45-75 mph I would sometimes get a stutter like the throttle closed for a split second. Now, after installing a K&N CAI the dang thing is about undriveable. At idle no load the engine will not rev, step on the gas and all I get is a groan, pop pop groan slooooow climb in revs to @ 2000 rpm then quickly up to the fuel cut off. In gear , 1st or 2nd, trying to roll out off idle I get nothing more groan sloooow climb up to 2000 rpm then accelerates normally.
At speed in any gear when RPMs drop below 2000 rpm it will not accelerate no matter how hard I press on pedal. Up above 2000 rpm mostly normal unless I get out of throttle, then I get a bucking sensation from engine. I can pull away from stop if I give lots of revs and slip the clutch....not so good for clutch life...The MIL is on, P0113 IAT high bypass. Cleaned old MAF no difference. Replaced MAF no difference. Got a too rich code also but cannot remember DTC. I have also checked for air leaks after the MAF and it all seems rather buttoned up.

The clutch in my ac compressor is not releasing causing it stay on all the time and not cycle and get hot and freeze up the system. Also pulley seems to be angled like it's not sitting straight. Can I just replace the clutch on the front? if so what's all involved. I need to do the entire compressor?

I have a 2005 Ford f250 Diesel 4x4 with - unfortunately - the crappy 6.0 engine. Yesterday my Daughter parked in the yard and this morning the truck not only will not start but will not even turn over. I thought maybe the batteries were dead but that is not he case. When you turn the switch on you can hear the pump start up but it will not turn over? All the lights come on and the bell comes on when you open the door and the dashboard lights work but the thing will just not turn over. I am assuming this may be some type of electrical issue or something but whatever the problem is it just came out of the blue. Ford imo should have recalled this engine.

I have an 05 f250 with 109k. Recently I turned off my truck, waited about 45 min or so and upon returning the truck would just crank and crank with no fire. After waiting about 4hrs the truck started right up like nothing was wrong.
Yesterday it did it to me again. This time I have it a small shot of starting fluid and it fired right up and ran like a champ all the way to the shop..... I got the call today from the mechanic saying I have 5 injectors that are bad, 2 glow plugs and harnesses. His quote was 2400 out the door.

I had this truck for two months no problems yesterday went on a small trip about 50 miles in on ,the hwy. I start seeing some smoke and then no power turned off & on engine several times a little hard starting no power at all I put the pedal to the floor It barely moves ran into another super d. guy he said fuel filters , I turned around and crawled back home and changed fuel filters still no power. no codes "don't no where to start".

I got a problem with my Ford F250 6.0 Diesel. The truck got a new HPOP but still wont start. ICP show everything between 15 und 75 PSI, it raises to 75 PSI max during cranking. The IPR shows 84,75% during cranking.
We get the code P0270 and P2285 in exchange but never together. We already checked the FICM but it looks good on the inside. I now ordered a new ICP sensor....

I have a 2005 F250 6.0l. I have no speedo and the ABS light is on. It was intermittent at first. It would go on and off if I hit a bump or braked quickly, but now for the last month the light has been on constantly.
I have tried the following to no avail:
1. check the harness to the VSS (rear ABS senor on the pumpkin)
2. replaced the VSS on the rear
3. check the lines from the vss for resistance and open short (and short to ground)
4. checked the HS-can network (pins 14 and 6 in the DLC to the respective HS-can + and - on the module) both have less than 5 ohms (about 3 ohms found) and no short.
5. checked the resistance of the network itself across pin 4-16 and found 60 ohms.
6. ran scans with OBD fusion for ABS (no abs found)
7. ran scans with forscan with laptop, does not detect ABS unit neither new or old module. note the TBC and IC both throw codes about not detecting the ABS.
8. check HS-can on the PCM as well as VSS wire from abs to pcm, no shorts or resistance.
9. check the number 11 fuse, (good) checked ALL fuses, only bad fuse found was trailer light number 20 engine bay. issue was a wire at the tailer connector was t-taped and not sealed leading to a short to frame.
10. checked the connector to the ABS module for power on both constant power pins, for open ground on both grounds, and power on run, all with in spec.
I've been diagnosing this for the last week, I am running out of things I can think of to check.

This is my first winter with my 05 F250 that has the 4wd controls on the floor. I'm just trying to figure out the proper way to put in in and out of 4wd. I did some reading and everyone talks about engaging the hubs, but my truck seems to have automatic hubs because the selector Is not on the outside of the hubs. Am I missing something obvious or am I just reading the wrong things. When I bought it at the end of summer, we tried 4wd out but only for a second and it would grind and be generally unhappy when we were doing it (while driving slow, and complete stop to go to low).
