I have turned wrenches on all kinds of autos heavy equipment and just about anything in between. This dag gone truck has me twisted all up. It does crazy stuff. One day runs great, get back in it the next day acts like the old non turbo gm conversion diesels. Got in it yesturday press the go pedal and it wont rev. Put it in gear or just sit there in park and hold your pedal down and it slowly takes fuel. WTH?? Bad fuel pedal, cp3??? Any ideals???
