Thanks for the response. When the coil first went out I drove like 3 miles to the local parts store pulled into the lot popped the hood and the cat was glowing red
..... Let it cool down replaced the plugs and drove another two miles parked it in the garage and did not run it again until all coils were replaced. You think I burned up the cat since it was glowing red or do you think theres a possibility its okay?
