hi im new here, i own a 02 deville and was wondering if anyone could help me. my deville has terrible multiple misfires. i changed the plugs today hoping this would work but it didnt. while on the lift i also noticed the cat was glowing red hot, so i disconnect the cat and drive up the road. it still feels like a 4 cyl. im guessing ignition mudule, but would this explain the red hot exhaust? any info would be appreciated and thanks for reading my post.
