you might try grabbing the wiring harness on the drivers side, kinda laying on the fender well. jiggle it around a bit, and see if the idle revs, or dies. also check all plugs, get some dielectric grease, adn grease the plugs up. these are things chris(climbcovey ) has done. i think hes about got it whiped.. are you getting a check engine light, and if so, what are the codes???
