Why would my catalytic converter get red hot in my Lumina?

The catalytic converter in my Lumnia gets red hot.

Catalytic converters are designed to get hot to burn off the excess emissions before they are released as exhaust. Usually there is a heat shield to prevent you from seeing it. If it seems to be getting unusually hot it may be clogged.

This could be a fuel problem, as engine sending too much raw fuel to the cat to burn. Check also the spark plugs or wires it maybe one of the factors. Running with a cat burning red hot for long can cause the cat to fail, and in worse scenarios even burn through the floorboard.
