Check Engine Light... gone
My check engine ligh came on not very long ago. I had the code read immediately, which revelaed I had "low threshold" in bank 1, which more than likely means that an O2 sensor had gone bad. Well, yesterday onmy way to church I noticed that my CEL was gone. I don't know how to feel about this -- should I treat it like it is all fine (I had suspected that maybe the connector had come lose on one sensor) or should I really worry, since now I don't know if the problem persists, only that now I don't have visual confirmation/feedback form the car?
