So. Check engine light came on a while ago. My car was being a gas pig. Read my manual, and it suggested that if my car was being a gas pig, that my light may come on. So I gave it a tune up, replaceing spark plugs, airfilter, replaced fuel filter like 6 months ago, replaced pcv valve. Cleared the codes, and it drove fine for a few days. Then the code came on again. My mechanic scanned the codes, and it was runnin lean in banks 1 and 2. However the o2 sensors seemed fine he suggested just clearing the codes, so I agreed. Check engine light came on again, exact same codes. I had never had the o2 sensors changed, and he was not 100% sure that it was the sensors, but felt that it was more then likely the case. So I took the car home and to save my self the labour, I changed the sensors. Car ran great!! Then the check engine light came on again today. I dont understand... Why would the o2 sensors indicate lean, and no others sensors malfunctioning. I have no mods, other than removal of the air silencer a few years ago. I would think that if it was the MAF or EGR that they would also throw codes. But I only seem to get lean codes from the front two O2 sensors.
Advice, please!!!
On a side note, I would like to thank Ford for making the front two O2 sensors so easilly removable " jerks". The drivers side was easy, the passenger side seemed to require alot of cursing and swearing!
