The air mass meter is a slight misnomer as it doesn't directly measure air mass,it measures air volume. The air mass is calculated by the ECU using the volume reading and the intake air temperature. Maybe checking IAT might be useful aswell as a ong reading here can skew the air mass readings. The IAT sensor is usually built into the AMM unit. Hope this helps and as always I am open to correction. Paul Galvin.
