check to see if the exaust is resticted, has the cadilatic coverter made any noise. if it has rattled it could be getting ready to go it will get red hot because of the exaust restriction.

Suggested Repair

Check for a restricted exhaust, especially a rattling or failing catalytic converter. Also verify mixture control and whether the check engine light is on.
