Your Mazda Protege's Air Flow Sensor determines the mass flow rate of air that enters the fuel-injected internal combustion engine. The air mass information is necessary for your Mazda Protege's Engine Control Unit (ECU) to correctly balance and deliver the correct amount of fuel to the engine. When there is a problem with the Air Flow Sensor, symptoms often include: Engine having problems starting, Engine Stalling, Hesitation and Jerking during Acceleration, Excessively Rich or lean Idling.
Ensure your Air Flow Sensor is properly functioning for Optimal Engine Performance
