Ok let me explain, my check engine light is on and it says Bank 1 and Bank 2 are lean. Now let me tell you what all I've done. Cleaned my MAF, Replaced the fuel filter, Replaced the air filter and I replaced an 02 sensor a while ago. When I replaced the o2 sensor the computer told me exactly which one to change, therefore I don't think it could be that. I've talked to 3 different very experienced car guys and each have told me different things- an o2 sensor, intake manifold gasket, air hose leak. Anybody had this happen to them and they couldn't figure it out?
