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.

Ever since having the EGR delete done, the oil temp has been LOWER than the coolant temp. I am assuming this is bad info from the sending unit? They are reading with in a degree of each other at start up, but when at operating temp the gauge will read lower. Before the EGR delete I had a delta of about 4-7* oil hotter than coolant.

Bought this truck back in September. I thought the ball joints were going out. So decided to replace everything i would think of. The ball joints, hub bearings, all the tie rod end parts, sway bar links & bushings, and the seals around front u-joints. Now i still have the same rattle. Sounds like a piece of metal rattling in a tube. Really it sounds like the ball joints are out, which i know they are not. Also i greased them again (Just to make sure) and no change.

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 :: Engine Bogging Down / Dying And No Response To Gas Pedal
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.
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.
Ford 6.0L Power Stroke Diesel :: 2005 - Lost Throttle Response - Died?

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?
Ford 6.0L Power Stroke Diesel :: No Throttle Response In Gears After Injector Install
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.

Ford 6.0L Power Stroke Diesel :: 2004 Excursion - No Response When Step On Accelerator Pedal
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.
View 8 RepliesFord 6.0L Power Stroke Diesel :: F250 - Slow Throttle Response Lower RPMs
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.
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 6.7L Power Stroke Diesel :: No Turbo Pressure?
Weird thing happened today. Was out running errands, and upon pulling out into traffic I felt the truck lag a little. I figured it was the typical trans hiccup we all experience from time to time. As I continue driving, I notice I don't have any turbo boost.
I'm cruising around 55-60 and when I slowly give it gas......No boost. I stomp it and the turbo gauge slowly climbs to about 12 psi. At this point I waiting for the truck to throw a warning message and none came.
As I'm reaching my destination, the speed limit is 30 so I'm just putting along and any acceleration I did, the boost needle wouldn't move. I arrive at the store, and when I got back in 5 minutes later and drove off, My boost was back. Truck operated normal for the 25 minute trip home. I thought a similar thread was started but I couldn't find it.
Ford 6.0L Power Stroke Diesel :: Turbo Up To 30 Psi Normal?
My truck is all stock and I am running in performance tune? And my friend the former owner said I need to let her loose about 75 percent of the time I am driving it because it's my DD and I do not tow anything on a regular basis. I do not want to stretch my bolts by unnecessary pushing, I don't know if I'm even pushing it hard but I normally get the turbo up to about 30 psi is that to much?
View 8 RepliesFord 6.0L Power Stroke Diesel :: How To Get Oil Tube In Turbo
Still working on this E450. Now, I'm trying to get the turbo back on and I don't know how the heck to get the oil tube in.
There's so little room that I can't lift the turbo up. Just getting it in and out is a chore. I was able to pull the oil tube out with some difficulty when I was removing the turbo, but if it put it in first, the turbo won't go over it to get back in. If I leave it disconnected to get the turbo in, I have no way to reach under it to get the oil tube back in.
I only messed with it for a little while - it's physically difficult bending over inside the van to wrestle with it - and will go back at it first thing in the morning. I know there's gotta be a way, I've just never done this before.
Do I stick the tube in the turbo first, in the engine, or neither until I got the turbo in place?
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 6.0L Power Stroke Diesel :: No Response When Pressed The Throttle And Started To Move At Signal Light
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?
