    Dealer said that the O2 sensors need to be replaced with a catalytic converter replacement. I can not think of any good reason why?? If the O2 sensors are still good, they should work on the new cat, right???
    Please help!
    Thanks

    you will need to check exhaust emissions to see if your old O2 sensor is working if the lamba is whong it will burn out your new kat
