    You probably can't tell if your catalytic converter is bad, if you had the experience and tools to tell, you wouldn't need to ask. Get the warning lights diagnosed by a Jag specialist, ASAP... Save yourself some money and misery by getting it checked now...
    The check engine light indicates that the computer has detected a malfunction in the engine/transmission control system and has diagnostic codes and data stored which would be essential in diagnosing the problem.
    A technician with a scanner can access the diagnostic codes and data and then be able to give you a diagnosis.
