I am a newbie, but I have a check engine light come on in my 1999 impreza outback. It is code P0103 which is mass or volume air flow circuit high input according to my tester.
as the air mass sensor is a few hundred I was wondering if anyone has any ideas on how to test the sensor without going to the stealership?
Also the car will not rev past 3500 rpm. is this because of the Air mass sensor?
