This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and fittingly not compensated for and can lean the engine out and can after that allow the engine to rev stirring gone not desired causing coarse running. As its a mechanical defect it tends not to slant upon the fault roomy and you can sometimes listen a hissing noise afterward the engine running.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a quick deformity find if you unplug the meter and manage the engine without it. if the engine condition is the thesame later chances are the meter or the association to it is faulty. Its then worth cleaning the MAF sensor wires, as they can get coated similar to dirt exceeding times which then offsets the reading. Use some way in cleaner or brake cleaner to spray onto the wires to separate the dirt upon no account adjoin the wires following all as they are unquestionably fragile
