Well, the bank 1 is good, the car didn't like me unplugging that at all after a mile or 2. Couldn't find the other one, but shouldn't it throw a code sometime when I'm driving? It never flashes the check engine light or comes on no matter hwta I'm doing witht he gas pedal. Checked the vacuum lines, the rest of them are good. I will try to check the other pre cat tonight if I can find the sensor. Its running better since I fixed the wiring harness, but I still think it can be better although I may be worng since its been so long since its run good. Can someone please help me out with the sensor connection for the bank 2 (closest to rear I'm assuming)?
