I've had my problem with P1128 and P1130 both coming on while sitting at idle.
There are many threads with P1128/P1130 that I followed to conclude that my MAF was bad.
In those threads, they describe the potential source as MAF or fuel or leak etc will reflect an error CEL for both banks; although the discussion does not negate the possibility of such influencing only one bank, is it possible that MAF replacement is only a temporary cure and not THE SOLUTION?
