2005 Ford F-250 Repair Question
2005 Ford F250 no throttle response 6.0 powerstroke
After more than 20 minutes of city driving or more than 30 minutes of highway travel the trucks rpm gauge begins to surge. In the city at stop lights the truck will bounce betwen 500 rpms to 1100 rpms. Then as i accelerate there is no engine response. with the gas pedal to the floor the engine is still idling. After i idle to the side of the road and be patient it responds after about 5 minutes. Yesterday same problem occurred except i had to park overnite on roadside and then the following morning it started up no problem. what could be causing this?
On interstate travel the battery light has been coming on whenever I accelerate even the slightest amount. and the batteries were replaced this last month.
Took the truck to Auto Zone for their engine scan services and since the check engine light wasnt on they wouldnt scan it. All during these issues the check engine light has yet to come on.
Is this the diesel motor? Which one do you have if not? Turbo? non- turbo?
There is a calibration update for various drivibility symptoms.
Check for mini fuses mis installed in the power distribution box under the hood:
Has the alternater EVER been replaced?
Need engine size I can go a little further on this one.
The engine is the 6.0 Powerstroke diesel engine.This also is the turbo engine. The alternator has never been changed in the vehicle.
matter of fact other than routine maintenance nothing has been changed on the vehicle to my knowledge.
Another issue that i expierenced today in addition to aforementioned ones was that the the turbo psi gauge would barely move whenever I would accelerate. Didnt matter whether it was a gentle or hard acceleration it was like the turbo wasnt engaging at all. I am at a complete loss as to what is causing this. if it is something as minor as sensors or fuses or a major componet failure

In this case, I would find out it you have the latest and greatest software calibration on the truck. There is a TSB on drivibility
There is another TSB on coking of the turbo charger.
The latter tsb gives a procedure on inspecting, I can send it if you like.
yes please send it i would greatly appreciate it...

Did the service bulletin help out? I have same problem. Yesterday truck would only idle even with peddle all the way to the floor.....then when I turned it off and restarted it idled at about 400rpm til it died. Waited 20 minutes and flawless operation.
