My 94 k1500. 5.7 tbi. Is having some driving problems. Idling the truck is sound, but from first gear to 3rd it is kind of all over the place. I can't hold a constant speed. It fluxuates speed and rpm. I had the motor rebuilt and the machinist put a bigger cam in the truck but I don't know what to do with the pcm. Where it is, what it does or anything. If you could help me figure this out I'd be greatful
have the same problem?
