(Brand new here....HELLO!)
~Concerning a1998 C2500 with Vortec 5.7L ~
Yesterday while driving at 60mph with cruse on the truck started to accelerate out of control!!! Tried to turn off cruse - no change. Hit brakes - nope! Ended up throwing it in to neutral turned off engine with key and was able to (safely) get to shoulder and stop. (From middle lane in heavy traffic!)
Thinking the Cruse control was at fault, I pulled the fuse. Restarted engine only for it to immediately race like a bat out of hell! Killed engine then decided to poke around under hood. I found the throttle body valve stuck open ~but the two cables going to accelerator pedal and cruse module did not seem to be catching. After checking everything I could think of engine started normally......BUT.....now it is running like crap. It also seems that the Transmission has gone in to 'limp mode' , does not want to shift out of 2nd. Engine is Sluggish - no power and kinda 'rattles' like a diesel. And wants to stall out (as if it had a carb with idle set to low).
I am not sure where to start trouble shooting?
Could this be caused by a bad T.P.S.?
Engine dead?
Any help would be great!
