I am wondering what is causing my car to run rich. Correct me if im wrong but my CEL light was going off. I took my car to autozone and the computer scanner they had said its high voltage from bank 1 on oxygen sensor 1. from high voltage i see that it means thattheres no(or very little) oxygen in the exhaust from excess gas being burned. what I am wondering is what can i do or check to see if something is causing the readings like that(like injectors or what other things could be checked. thanks

Perhaps the O2 sensor is bad.
