Well after spending more $$$ for an expert to tell me I had a bad 02 sensor. I went and bought one on line, lot cheaper than the local auto stores. Anyway $74 later I get it in the mail, it is a Denson brand and the same that was in it (OEM). Well after I installed it by the manufactor recommendation I still have the ENGINE LIGHT ON. Oh well I guess I will keep spending and replacing parts till I get it right. BTW my friends Rod and Nash told me this would not fix it. They was right. and the paid expert was wrong.
