check engine light comes on somtimes after full throttle then goes away?
my check engine light goes on some times upon startup and/or after full throttle. Once i let off the gas the light comes on and the truck will not respond to the gas pedale, it will stay at a clean idle for like 10 seconds or so and not do anything if i give it gas, kind of like a fail safe mode or something. i removed my airfilter thinking it was getting clogged but that didnt stop it. I also plugged in a code reader and it doesnt show any codes present. There is also no chip or tune in the truck, it is a bone stock 2002 7.3 psd. Any ideas?? Thanks a bunch!
Re: check engine light comes on somtimes after full throttle then goes away?
The MAIN thing is if you have a SES light the truck is trying to TELL You where to look for the problem!!! Get the codes pulled and go from there, Unless you have money to throw away!
