Hey guys, I'm getting the code p0420 that I've had checked from autozone a couple of times. I've had a cat replaced within the last year; It says that the code could be from either my cat or o2 sensors, but why does it come off for a week then come back on for a couple of days, then go back off? odd.. since it's nothing serious should I just get my emissions tested while it's off :rolleyes:

Re: P0240 Comes off and on
Same code mine popped while I was still running the stock exhaust. New Cat and Magnaflow on, erased the code and it popped again, so I'm guessing mine is an O2 sensor, just don't know which one (hope someone here does). Mine just stays on all the time though, so wouldn't know about that.<a href=\"http://www.cardomain.com/ride/2182744\" target=\"_blank\">http://www.cardomain.com/ride/2182744</a> <br /><br /> </font><blockquote><font size=\"1\" face=\"Verdana, Helvetica, sans-serif\">quote:</font><hr /><font size=\"2\" face=\"Verdana, Helvetica, sans-serif\">I\'ll procrastinate later...</font><hr /></blockquote><font size=\"2\" face=\"Verdana, Helvetica, sans-serif\">
