Anything can cause it, go to Auto Zone or Oreilly's part store and have them hook a Code Reader up to it, it will tell you exactely what caused it, and it's free!!!

P0420 is most likely a bad drivers side cat - GM extended the cat warranty on the 00-02 LS1 F cars to 10yrs/120K.

Haha, I didnt know what was wrong...I'm still use to having old motors and not these LS1's....I just checked everything that i could think of that had anything to do with the engine, but my tire pressure is all good lol....but I takes jokes pretty good...I had to go to a dealership and they scanned it for me. it was an O2 sensor that was out. The guy said something about the front O2 sensor on the passenger side, nothing about the rear O2 sensor? Ive just seen the one thats on my headers, where would the "front" one be? I dont know if having an EGR delete makes any difference or not.
