A failing mass air flow sensor can show up as a rough idle, hesitation or a check engine light. If the sensor is the cause, this one replaces it. First, look over the connector, its pins and the wiring for damage or corrosion, with the engine off and cool. Each vehicle takes one sensor, and this listing is one.
