I have a 2000 F250 7.3 diesel. After sitting in heavy traffic it lacks enough power to climb even a small hill, if I turn off the engine and sit for several minutes it will resume normal engine capability. What is my problem?
Welcome to FTE. How does the engine run when you don't have any power? Is it rough, spit and sputter, shake? When you mash on the skinny pedal, do the rpm's rise like they should? Is your engine oil full?
You could have a bad oil temp sensor, or you are getting the oil too hot where the PCM is in limp mode. Only a speculation from what information you have given though.
Thanks a lot to those of you that took the time to reply.Im having a reoccuring problem with my 7.3 power stroke.She's been a good truck and has given me few problems.At just under 230,000 mi.the only major issue at least as far as the drive train has been the torque converter at around 200,000 mi..By no means a show truck , as I have to haul an auxillary fuel tank and heavy tools in order to operate and maintain heavy earthmoving equipment.I've done all that I believe to be the nessesary maintenance,and I do'nt abuse her.However recently as posted earlier after having to sit in traffic for long periods,which I have to do all to often as I live and work in the Wash.DC. area.The truck seems to be starved for fuel .Even if I floor the accelerator the engine RPM's reach barely above an idle.Although the engine seems to run rough it's not extreme when the problem occurs,It just doesn't have any gettyup go.If I pull over and sit a while I can eventually restart the engine and resume normal operation.There is no warning or check engine lights or abnormal temperatures.A mechanic friend sugested a faulty fuel pressure regulator.But these are quite pricey and I don't want to just throw parts at the problem.I would appreciate any knowledgeable opinions.
The fuel pressure regulator is only a spring in a housing. You can replace it for $40, but that is not your problem.
You may have issues with your throttle pedal as it is an electronic signal that makes her go.
It would best to try and diagnose it in person, so if you have a trusted mechanic, you may want to run it to them and get some basic tests like fuel pressure checked.
How old is the oil that you are running?
Do you know if the engine temp is hot or warmer than normal?
