Code 420??
I was wondering if anyone knew what causes this code. The description is something like insufficient catalyst (bank 1) or something like that?? I have a Random Y-Pipe with their cats and catback system, but no headers. It doesn't seem to hurt performance, but I was just wondering how I could fix it. Also, I reeplaced my two rear oxygen sensors about a year and a half ago.
Thanks,
Joel

Re: Code 420??
I recently had this code. Took it to the dealer and they replaced the driver side Cat. I used to hear a tin can like rattle at WOT. After they replaced the cat the rattle is gone. My cat must have broken up inside somehow <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> Not sure how it broke but it did.
