Bad MAF sensor? | The Nissan Club

· If the maf is going bad and it''s flagged by the ecu, you won''t be able to rev over 3000 or so. The ecu will effectively take the maf out of loop and rely on it''s hard map. I''m guessing that you have a vac leak somewhere. The fact that the a/c returns it to normal makes sense because when you''re running the a/c the ecu runs the car a bit more rich.
