1996 the main culprit like mentioned above would be the throttle position sensor. To reset the computer disconnect it for 15min, usually how long it takes me. My 96Z28 has the same ODBII computer just different program. There's alot of info on some GTP forums and camaroZ28.com.....its all GM there. Too bad you dont have the new SC 3800's. With some simple mods they are capable of low to mid 13's Good luck
