  1. Generally when the catalytic converter is glowing it is from an excessive amount of unburnt fuel getting to the converter and burning there. This is an indication of a RICH condition.
    Start with the check engine light codes if you have any post them below in the comments. Could be as simple as a tune up or a vacuum leak.
