I have a 1996 Cavalier Z-24 and Friday night my cat and restinator was glowing red so I took it the cat went bad. Ok so I had the cat changed and now the car lopes real mad and sounds like a pissed off go kart. I checked the ICM and the ignition along with the egr value changed the O2 sensor and I let it run even though it was still running rough and the new cat got red again so I said maybe the resinator is stopped up but no the damn thing is still running bad any suggestions would be appericated.
