1994 GMC Top Kick 7.0L Cuts out, Stall, Misfire
Posted to GM Driveability on 5/22/2003 13 Replies

Vehicle bucks, and back fires when hot, intermitently. But getting steadily more frequent. Runs better when the est connector is disconnected, but still not good. No power. Moving\tapping the ECM has no effect.
