Ford 6.0L Power Stroke Diesel :: 2004 F250 Stalling / Loss Of Throttle Response And Won't Start
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.
Ford 7.3L Power Stroke (1999-2003) :: Sluggish / Slow Response On The Road - Throttle Surge
7.3 2001 model starts ok at 32-35 F. Feels a bit sluggish / slow response on the road. Reach a hill after 3-4 miles. Engine temp then beginning to go above low level mark. 100 meters up the hill, going around 30 mph there is a sudden surge in the throttle although my pedal is steady. Going back a few minutes later, on flat ground at bottom of hill and with no accelerator pressure, the engine suddenly stalls. Starts fine again after I stop. The same history actually repeated on two separate days recdently on the same hill. CPS is recently replaced. Had some jerking before that, but not the behavior explained above. Current CPS is Delphi light grey. Recent fuel filter change and oil change as well

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.
Ford 6.0L Power Stroke Diesel :: Shakes At Idle / Poor Throttle Response
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.

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

Ford 6.0L Power Stroke Diesel :: 2007 F350 - No Throttle Response - Code PO231
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.
Ford 6.0L Power Stroke Diesel :: Air Leak / Slow Turbo Response / Code P0299
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.

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?
View 1 RepliesFord 6.7L Power Stroke Diesel :: F350 Shifting At Lower RPMs
Just bought 2 new F-350 with 6.7s for a service truck and feed truck. I have a 2011 6.7 so pretty familiar with it. I noticed both these new trucks shift at a lot lower RPMs. At times if going from pasture to pasture I have noticed the tach at 900 rpm in 6th gear. My 2011 doesn't do that, it shifts at a higher rpm. Both of the trucks have been deleted, and I have a SCTx4 tuner in each truck and have both tuned to the lowest setting, Tow 40HP. Is this a fuel economy thing?

My 6.0 has been leaking oil for a couple weeks now, possibly longer judging by the staining underneath. Very slow leak. 1 drop hits the ground when I get off work and go to get in the next morning. It never really reads off the dipstick a drop in the level. I had to top up the oil yesterday but that is from about a 2-week span. But I want to get it fixed. I've attached pictures of where it's coming from and was hoping to get pointed in the right direction. Also its a 05 f250 and coming from the driver side.

I currently have a 2006 F-250 6.0 with 187,XXX.
My problem that i am having is that the transmission recently within a couple weeks started acting weird about the same time 3 of my fuel injectors started failing. When i start up the truck and put it into drive it takes about 3-5 seconds to shift. Once it's in drive it runs pretty well but it will start shifting out of normal when i go to accelerate. Also when i go to slow down sometime the transmission shifts hard to a lower gear. I also have a video of the sound that it had started to make since its hard to describe.
Here are attached videos and photos. I want to hopefully fix the problems myself so i can learn more about my truck. I am going to handle the fuel injectors here soon since 2 are failing and ones about to these have been causing the truck to shudder at around 47-53 mph but after that its fine.
The transmission is stocked and never been altered, i do admit for 3-4 years I have changed the fluids or filters.
The truck is bullet proofed, sct tuner, upgraded turbo from stock, 4" exhaust, head studs and new everything when the engine was rebuilt and bulletproofed.
I plan on going to ford tmw to have them figure out the problem and hopefully its just solenoids so i can fix it myself. I have a link posted also where you can hear the noise it has been making when in R P and when shifting going down the road and it is a automatic.

Ford 6.0L Power Stroke Diesel :: 2006 F250 - Grinding When Ease Into Throttle?
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.

i got a 99 F250 powerstroke with 148K on its clock, i have a couple issues that i cant find a definitive answer for, 1 just started recently, Its an automatic and when it shifts into third around 40 mph the rpms drop to 1200-1300 or so, its done it since i got it, but recently it wont accelerate like it should or used to do, i have to put it down and make it downshift to recover.
Now I have no CEL. and it is still running perfect just has very little power, I do have a 4 inch turbo back exhaust and have a TS 6 position chip with i usually run in +50hp mode, but it does this in all positions. Now issue 2 is when its 30 degrees sometimes it will not start. It'll turn over with now fire. but if i cycle the key again it'll fire right up like a champ? It has a 4 month old starter and batteries and a month old alternator and i have tried several CPS' and Contently check the connections.

I have a 2012 F-250 6.7L w/8K miles. I have been struggling with this issue for 6 mo. The engine feels like its missing at low RPM. I would equate it to the feeling of a bad coil pack in a gas engine. The boost indicator drops to 0 for a split second then recovers. The dealer says they can't find the issue but went ahead and replaced the turbo. After the turbo replacement It got worse. This is an intermittent problem with no codes.

The ford dealer in Las Vegas replaced my turbo with a remanufactured one. Coming off the line (like quickly pulling into traffic) it goes flat on power until I get a few RPM's. Even with the old turbo it never did that and I drove it for the last 30k miles with it throwing the low turbo boost code. They put a little over 100 miles on it for road testing (I did have other things that they worked on. {4x4 2006 F250, 6.0 engine, 110k miles and I bought it new}....
View 4 RepliesFord 7.3L Power Stroke (1999-2003) :: Only Idle / No Throttle Response At All
I have a 99 F450 with the 7.3L in it. I brought it home the other day and parked it. Later I went to do something with it and I had no throttle response at all. I checked the wiring going in and coming out of the throttle position sensor. I have approx. 5 volts going in and the voltage sits at about .5 volts and rises as the accelerator is depressed on the outgoing wire. The other switch on the pedal is open and does close when the pedal is depressed, so it seems those are fine. I'm not sure what I'm supposed to have on the 3rd wire that goes to the TPS.
I have a Bully Dog tuner and it shows an exhaust back pressure sensor error and a couple of voltage errors to the accelerator pedal. I read somewhere that someone had an exhaust sensor short out and it starved the accelerator pedal from voltage or something like that but I do have good voltage at the pedal going in and out. I ordered a new sensor and tube.
If the exhaust pressure sensor was shorting out and I unhooked the wires could that make the pedal work if the sensor was the problem or would the accelerator pedal not work at all without that sensor being connected? (The old tube was somewhat plugged up and I saw it had a small rust hole in it)
If it's not the sensor, what else can I check? Where can I check under the hood to see if the wires from the TPS are getting power to where they need to? I assume they go to the computer and that tells the pump or whatever to give more fuel.
