Mass Airflow Sensor Replacement
Problems with mass air flow sensors are common. A bad or contaminated sensor can cause a wide range of problems, including stalling (especially when the engine is cold), misfiring, and poor acceleration. A problem with the MAF sensor often causes the check engine or service engine soon light on the dashboard to illuminate.
To replace the MAF, the electrical connection and screws (or clamps) securing the sensor are removed, and the new sensor is installed.
