    I have replaced the thermostat and collant temp sensor, as well as the
    lower O2 sensor but the CUL and the errors remain and I can't clear
    the errors wiy my OBDII. The car has about 110k could the catalitic
    converter be bad already?

    Anyone have any other things that I need to chack or replace.

    This is my niece's care and it's due for state inspection in NC and
    the CEL can't be on to pass the OBDII check.

    Thanks in advance!
