Faulty MAF? Airflow Quantity Measurements
I've been having some doubts about the condition of my MAF, below 3000 rpm the throttle response doesn't seem to be as good as it was and disconnecting the MAF gives a noticable by not huge improvement.
All the ducting is in good order and the circlips are tight. The airfilter is new.
Running multiecuscan shows no error codes (except when the MAF was disconnected) and removing the MAF and cleaning it with Airflow Sensor Cleaner increased the air quantity from 15.4 kg/h at idle to 17.1 kg/h but no change across the rest of the rev range.
The recorded values were:
Idle 17.1 kg/h
2000 rpm 20.7 kg/h
3000 rpm 35.3 kg/h
6800 rpm 134.8 kg/h
Does anyone know if these values are in the correct range?
