Overtime the factory MAF sensor can fail or accumulate dirt and oil causing the vehicle into some running issues or light up a CEL (Check Engine Light).
If your vehicle is running rough, hesitating after starting or experiencing poor fuel economy then you may have a problem with your mass air sensor. The MAF Sensor can easily be located beside the air intake box inside the engine bay.
