Thanks for the help. Google returned a completely different page with very little info when I tried it.
I did install headers 2 months ago............doesn't sound like anything to be worried about. How do I reset it?
Can anyone recommend a basic code reader (not a tuner) that allows you to reset also?

Codes 420-430 are a result of your headers and hi flows. The 02 sensors are detecting too much left over from the cats. Anyway, it happened to me right after the headers were installed. I bought 02 sims from a forum member (cbrf4i1) and now over 8,000 miles w/o a code. Inexpensive fix for a simple problem.

On a more serious note, The best way to eliminate the problem is a good LS2 tune. My suggestion would be to call Bobby @ LG Motorsports http://www.lgmotorsports.com/catalog/index.php (forum vendor/tuner) and set up an appointment to have the car tuned. This will change the settings so that the O2 sensors won't throw a code. Gets rid of the second gear lock out too, etc. Yeah, I know it means driving in to the Dallas area. What can I say ?

I had the same issue about 2 months after after I installed headers as well. Curious if you know if your installer bypassed the rear O2 sensors. Anyhow I purchased the Innova 3100 OBD2 code reader for about $70 and quickly cleared the code and reset the MIL. Hasn't come back in 4 months but ready if and when it does.
