Ford 6.0L Power Stroke Diesel :: Engine Bogging Down / Dying And No Response To Gas Pedal
Sep 16, 2016
Recently I have encountered another issue. Truck started up fine, at first stop light and truck was bogging down, RPMs jumping up and down slightly and sounded like it was going to die. Light turned green, gave it gas, no response. Gas pedal was dead. After restarting the truck I was able to give it some gas until I came to the next stop light and this repeated. Eventually a few moments later I got a check engine light. Drove home this way, seemed to be working fine as long as I was actually driving and not stopped.
All the parameters looked ok except for the battery, that jumped up and down in volts as the engine sounded like it was bogging down then eventually died. New batteries put in approx 2 months ago. The check engine light is showing "P0299 turbo/supercharger underboost". I have attached an image of this check engine light according to my monitor.

Ever since I've had this truck my parking brake has acted like this. My buddy has an '03 and his acts the same, but I figured I'd ask the question.
9 times out of 10 to set the parking brake, the pedal goes almost to the floor and doesn't seem like it really does anything. The other 1 out of 10 it goes half way and feels like it actually sets. Is this normal?

i have a 04 ford excursion 6.0 with the egr delete, was stopped at a light to make a left turn, when i stepped on the accelerator pedal nothing happened as the engine was just idling. i pumped the pedal around 10 times and finally got the engine to rev up. i just got this excursion and don't know to much about the maintenance on it. i am going to drain the water and change the two fuel filters. my neighbor is familiar with diesel engines and he said to look at the throttle sensor. i have run this engine up to 900 miles and it has started and run perfectly. i believe the usual maintenance like oil changes etc were done on it. would any error codes show up even though no warning lights on the dash.

I'm a new Ford owner and my 2012 F250 is my first diesel. Recently, my truck has been having a problem with the engine loosing power, bogging down, shaking-pinging, every once in a while, like 1-2 times a week. When it happens, I can barely get the truck to do 50 MPH. It sometimes happens when the "cleaning exhaust filter" message is displayed, but also happens when it's not displayed. I recently read on the internet about HPFD failures.
What may be happening to my truck? Could it need Cetane booster? Also, how about scheduled maintenance. The owners manual (diesel supplement) says to do the maintenance once the message center says to change oil soon. The dealers here in AZ are pretty much saying 5 months or 7,500 miles. On my other trucks (which were gas), I would stick to what the owner manuals said because I thought how could they deny a warranty claim if you're sticking to what the manual says.

My 6.0 with 178k on it just started to have issues today. Low power. When I hit the pedal hard the motor revs and the truck barley moves. When I baby it it goes up to speed and shifts fine. Overall lacking power and not going anywhere. No CEL on. Turbo spools and seems to be ok.

I'm having some serious trouble with a 2000 4Runner with the 5FVZFE V-6 with 165,000mi. The engine is bogging down/ sputtering and dying on startup, won't drive over apx. 20-30mph, doesn't seem to want to shift up or down, and won't rev past 3000rpms, stopped or driving. I've been a mechanic for awhile and never seen this issue before. But here's the kicker... I'm in bfe Afghanistan, have almost no access to parts (if I do it takes quite awhile to get them and even the easy stuff is hard to find), no diagnostic comp, and only the tools in my toolbox, air compressor, and solvent tank.

I own a 2000 F250 7.3 Powerstroke 4x4. The only aftermarket engine modification I have is a Tymar intake. The problem I'm having started about 6 months ago in a very erratic fashion. I would pull up to a traffic signal and as the light changed to green, without warning the truck would have no throttle response. The engine was running fine; there was just no response as I stepped on the accelerator pedal. Usually when I put the transmission in neutral, revved the engine a few times, the throttle would come back on line. This happened 4 or 5 times over the summer and then went away completely until today. Today it came back with a vengeance. At one point I had to shut the engine down completely to restore throttle response. It's a bit unnerving when it happens in the middle of a busy intersection. I was told that it may be the throttle position sensor. Does this sound correct and does it need to be replaced?

Having some problems with an e-350 dying when in gear and rough idle. Truck starts up after it dies. Vehicle acts like it is starving for fuel. I have check fuel pressure after fuel pump and getting 55psi. High oil pressure pump with in normal ranges. Cleaned and checked egr and it was in the closed position. Fuel filters have been changed. Injector buzz test ok.

So recently my bus has been having issues shutting down on us. It started about 6 weeks ago. My band was on our way to a gig about 5 hours away from home. We got about 30 minutes outside of our destination and the bus just quit on us. After sitting for about 30 minutes, and switching some relays around, its fired back up and we made it to our destination. The ride back home the next day was pretty rough; it happened 3 more times...
We took it out again about 3 weeks ago for a trip about half the distance and the bus quit on us about 20 minutes into the journey. It took about an hour or so of sitting on the side of the highway before it started back up. Rather than try to risk making the trip, we turned around, dropped the bus off, and found alternative transportation...
I should probably add that the bus sat for about 3 or 4 months during the ridiculously harsh winter we had here this year, as we took the winter off from gigging. It was unplugged the entire time as it was stored in a parking lot across the street from my shop where I couldn't plug it in anywhere...

I have a 2004 6.0 that has been pissing me off to no end lately. I has a random dying/no start problem. If it idles for ten minutes, it'll die sometimes. And if I drive it and shut it off, it won't restart sometimes. I just drove it three hours on Friday, shut it off and it restarted immediately. Drove it around town all weekend and it started fine every time.
Now driving it home and stopped for fuel 45 minutes in, and it won't start. I have all sensor readings in spec except for I have no ficm sync while cranking. I have about 5k miles on new hpop, injectors, ipr valve, icp sensor, oil rail rebuilds, stand pipes, ficm and engine harness and injector harness. No codes either. If it sits for a couple hours it'll start fine. I've wiggled as many wires as I can and it still won't start. I have rpm while cranking on my edge too. Don't know if that would rule out crank sensor or cam sensor.

So while driving just now the truck went down to idle and no matter what I did to the gas pedal the throttle would not change. The truck didn't die but would just sit at idle. It was like the gas pedal wasn't connected. About a minute later it surged a little and then I was able to drive like normal.
History- last week while at a red light the engine surged and then almost died. Light changed and I hit the gas....and stayed at idle...then died. Restarted and died two more times and then just drove like normal. Changed fuel filters and and checked fuel pressure. Under boost it was 38-40 psi. Idle it was 45. Cac tube replaced due to cracks.

I just recently got my truck back, My father and I switched vehicles due to need and distance's being driven. 2005 F350 6.0, 164,000 miles
I couldn't wait to drive it again, I spent hours detailing and cleaning. Well I go to start and noticed it struggled to start, and didnt seem to be idling right. I looked under the hood and it was leaking fuel from the Regulator. I left it parked and never drove it since he last did. I read around on these forums and I bought the blue spring upgrade kit.
Now I notice it shakes at idle a lot more than it used to, pretty bad at times. Then upon driving it shakes even worse upon acceleration attempts, and has very poor throttle response. I have to put it nearly to the floor and even then the acceleration is nothing like it used to be. Most of my trip was highway at 60mph, and anytime it would start climbing a hill it would shake pretty bad with the acceleration. When i let off the gas to slow down before braking it stopped the shaking.
So I read around on here and I went back and used the factory bowl and valve for the regulator, still had the issue. Next I went back and replaced the blue spring with the original, still have the issue.
I just checked the FICM and it is reading between 48-49 during key on, cycle, and cranking.
Batteries are great
Alternator only reads 13.6 at 2k rpm idle, but have not had charging issues.
My father says he never noticed anything wrong with it other than it occasionally missing out. But I don't see how changing the fuel pressure regulator would have caused this. Especially since I tried every combination of oem and aftermarket parts, ensuring that all the connections and parts were installed correctly.

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

I just completed installing rebuilt injectors in #2 and #4. for the 2nd time. The first set had failures with those two. After assembly, the engine runs rough which is understandable considering the air introduced. I can run the RPMs up while in neutral or park, however; there is almost no throttle response in drive or reverse. It will barely move and only slightly raises the RPMs. I am unable to drive it to get the air out until this particular issue is solved.
Prior to the tear down for #2 and #4, the throttle response was fine.
Current Codes:
P0272 - I am hoping this would go away once the air is gone.
Software:
AE w/ Ford Bundle (New to me)
Buzz test is fine
Power balance looks great
FICM logic and power are good
Skills:
DIY w/ limited electrical knowledge
Recent Mods in last 300 miles:
New heads
ARP studs
ICP
IPR
FICM w/ Atlas 40 from FICMreapir.com
Injector harness
HPOP
Chemical flushes
Oil Cooler
Leak Proof Ball Tubes
Stand Pipes
8 Rebuilt Injectors
Batteries
MAP Sensor
New Turbo w/ updated supply and return
All associated gaskets and orings replaced with the above
All OEM where available, except injector rebuild service

This is my first winter with my 6.7 and I've noticed that since the weather has been cold the motor rattles a lot more, doesn't seem to want to rev as freely and it seems like the turbo response is slower. I've noticed that my truck goes into exhaust cleaning more frequently, three times in the last week before Christmas. The transmission thumps on downshifts the colder it is. The first shift out of my driveway is between a thump and a bang. The dealer told me I'm not ready for a trans flush, it's not cold enough to need to use the engine heater and that some of the noise and lack of performance could be winter blend fuel.

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.

2007 F350 6.0L 230,000 miles
Yesterday, while driving home from a weekend out of town trip, all of sudden lost throttle control. Just went to idle while at cruise speeds, could pump pedal and no response. Then got pedal control back and seemed to run normally.
This happened several times. Hubby suggested moving the adjustable pedal which I did slightly. Although I was not using the cruise control, we had a sense that maybe it was engaging??? So I hit the off button a couple of times. After these two interventions, drove the last 80 miles home with no further incidents.
Today, we checked codes and had a PO231, Fuel Pump Secondary Circuit Low. I don't think that is our problem with above based on research, but we will look into fixing that too. We are thinking TPS or a position sensor on the accelerator pedal. We could replace those easily ourselves.

I am fairly new to working on diesel engines. I was towing a camp trailer and got a P0299, Turbo Charger Underboost engine code. I never gotten any other codes other than this one when towing. I decided to pull the turbo and clean the vanes. Everything seemed to go back together good but now I hear what sounds like an air leak coming from the turbo area. The boots on the intercooler pipe are in good shape, I only loosened the clamps at the intercooler and the turbo. Left the boots on the pipe. I have tightened the clamps around the exhaust pipe connections with no change. I also seem to get a slower response from the turbo and possibly not as much psi as normal (according to dashboard gauge). I have driven the truck five or ten miles trying to work the turbo and have not gotten any engine codes to this point.

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.

2003 F350 6.0 cc 4x4 with 291k... Not sure if I have a problem or not, it happened at a signal light: The light turned green, I pressed the throttle and started to move. As I pressed more, there was no response. Second later it took off and I have had no more problem. What the cause maybe?
