Check engine light comes on, rough idle wants to stall, gets a little rough during idle, at 4000 rpm starts to hesitate while driving.
Being from Western New York, My problem was caused by excessive corrosion in and around the distributor packs. This caused short condition which actually blew the fuel pump fuse. This must be a common problem, because it had happened to my previous truck. 1994 Chevy S10, same engine.
