    OBD ll Code P0420 @ for 2000 TA

    Have a SES light on and showing P0420 which reads DTC P0420 "Catalyst System Low Efficiency Bank One"
    Is this the O2 sensor or the cat itself or something alltogether different.
    Was Going to gut the cats one day but if it is failing I will just gut them now,unless the previous owner did it for me.
    The car runs pretty well but sometimes chugs when I give it about half throttle.
    Any ideas?
    Thanks

    P0420 is usually the cat - GM just extended the warranty on them for the 00-02 cars to 10 yrs/120K.

    My 01 WS6 did the same thing last month. I took it to the dealer and they put a new cat and o2 sensor on it under warrenty. But I had 64,??? miles and now just over 65,??? miles.
