    Could also be due to engine running too rich, burning oil, or an internal coolant leak.

    Any other codes besides P0420? mileage and maintainence have alot to do with failures. And yes as stated prior , to rich or to lean or misfire conditions all contribute to premature failure. Also the code may be set falsley due to other conditions. should have it monitored for function before replacement.,,,,,,,,,,,,<<<<<<<<<<<<< UNIONDALE H.S. class of 1980 >>>>>>>>>>>>>>>we rocked!

    We get a bunch of that. I think if one ask a question and gets an answer, it should
    be acknowledged.
