I did a header install about a month ago, so I decided to change out my old stock O2s with Bosch 13111s. After about 10 miles, my SES light popped up. I did not have the light before the swap. Does anyone know why this would pop up? I did double check the bungs for an exhaust leak but everything looks buttoned up, and no ticking or strange noises. BTW, I had my rear O2s deleted and tuned out already...only have the two up front on the headers.

THere could be several reasons for the ses light. Without knowing the code it's hard to tell. You can go to Autozone and get it scanned for free.

Yeah, I know that, but the code JUST got flagged right after I did the O2 swap. The code is going to be a left or right bank 1 code, or both.

People can start posting this and that about the Bosch sensors, but it's all rather pointless until you know for sure. Like Benner said, go to Autozone.
