Hey guys I was wondering if anyone has had their truck just start revving up by itself after a certain rpm? The truck is a 96 12 valve with a 13mm auto pump with unlimited rpm. It is fine till I hit between 3000 to 3500 then it will just start taking off, but it will drop off if I take my foot off the throttle. I have put extra return spring on the throttle linkage. Anyone have any idea what it might be?
