could is possible be the exhaust is to big and theres no backpressure? the guy before me cut the stock exhaust off before the muffler and ran dual 3" straight pipes all the way out the back.
My 1996 gmc k1500 has a weird thing occuring. after 3,000 rpms it feels like there is a rev limiter kicking in, could this be fuel pump? distributor? Its very weird and i want to get it fixed just not sure how to diagnose what it is...
