would a bad opti cause it to miss? i have a 96 z28 with the lt1. the plugs and wires are all new. i put a new opti in it about 2 months ago. ran awesome for about an hour after opti was kinstalled and after that it car started to miss. check engine light is on so i hooked it to a scanner. cylinder 3 is about dead. more misfires than fires. and cylinder 6 has a few misfires but not many
