Rough idle, hesitation or a check engine light can point to a worn mass air flow sensor, but the intake tubing and wiring can produce similar symptoms. Before replacing it, look over the tubing and the connector with the engine off and cool for cracks, loose clamps or oil film. A shop can test the sensor itself.
