Catalytic Convertor. Anyway, if you can limp to the parts house and get OBD codes that will eliminate much guess work. Bring the codes back here and one of us will help you decide what to do, I chose the word 'limp' intentionally because if your OBD detects a fault it allows you to get to a safe place without doing further damage to your drive train. The CEL is on?
