I have reviewed quite a few posts, and it appears to me the general concensus is that my O2 sensor is faulty. A vacuum leak would give me a rough or un-even idle wouldn't it? My last question. The scanner indicated Bank 2. But the clerk at Autozone said it is the one in the rear. The posts I have read indicate that bank 2 is the manifold closest to the radiator. Is this correct?
