Okay, this was fixed a couple days ago, but it's going in the wrong direction...
Both banks were slow response, (P0153, P0133) and i kept getting a lean code (P1151) and my car would start up fine cold, but would drop between 3 and 5 cyinders, and then die... I investigated all the probable causes for the SLow responses, but i can't figure out the lean part... any ideas? Might this have anything to do with the "headers" i had put on?
