Issues with new O2 sensors
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.
