New headers, SES light??
Its not anything "wrong", headers tend to do this now and then. In reality, if you were to drive around long enough (a couple of days), the light would turn off (after a few no code run cycles, the computer figures the problem was fixed). For the rest of the time you own your car (with headers on it), you will get that code now and then. The only way to really get rid of it, is to go in with LS1Edit and turn the code off.
I turned the code off because every few weeks (at least every 6 weeks) I plug AutoTap in and go drive around for a day watching everything to make sure nothing is broken/out of tune.

If it is P0133 and P0153. I've already posted the troubleshooting table for these. In this section. So a search would net you the exact procedure to fix this.
