Actually, My Mechanic was an ex volvo factory Mechanic for a rally car team. The drive sequence he gave me actually worked. The codes where clear but the banks have not reset. The rear defroster on put a draw on some system . What seems to have been the problem was I recently changed my complete PCV system and oil trap and the computer needed time to reset to the new condition. I did exactly as he told me and after the second cycle no incomplete banks. But who knows perhaps I just lucked out. BTW the rms leak has slowed to a couple of drops over night. Thanks for all your help!
