The MAF readings I think are fine. My idle values are 3.5 - 4.5 g/s typically. (The value shown on the picture is not at idle).
I have a couple more naive questions.
Since the STFT values are fine, I assume that the engine is adapting just fine and not running lean or rich when in closed loop. If the MAF is reading low due to bad/dirty MAF or additional unmetered air, would the car then be running lean in open loop, or does it use the last known LTFT values and hence be close enough?
What defines the idle range for DME7.2? Nothing in the data indicates why the code would have been thrown as the idle data always seems to be less than 11%.
