Slacken the hose clamps that hold the mass air flow sensor (MAF) /air mass meter to the intake boot and to the engine. Do away with the mass air flow sensor/air mass meter for examination, cleaning or replacement.


Check the mass air flow sensor/air mass meter wires in a direct light source. Look for any dirt build up that would hinder the engine computer’s reading of the air flow.
