When I try to accelerate my car (Hyundai Accent Hatch Back Year 2000 1.3L) it gave some misses of the engine and tries to stop the engine. My Mechanic said it is due to Mass air flow sensor failure and He can fix it using Air Flow Sensor of Nissan FB 15. According to him both sensors coupling accordingly except the pins of sensor. So he is trying to fix that manually. Is this correct or wrong? I am not an expert in Vehicles.
