Love my truck for the most part but....GM has replaced the injection pump 2 times also the lift pumps. Of course the truck just went out of warranty so im tryin to figure this one out on my own.... the truck under load between 2200 and 2500 rpm surges.. maybe 150 to 200 rpm consistently. hot or cold load or unloaded.with or with out AC . and ideas to check out. and btw can the paper clip trick be used for the codes on my 97 rig? Thanks !!
