    Very possible!! Yellow light on in dash? You can easily test this sensor but need to know about the light.

    Start engine, let it warm up. Tap on maf sensor with a screwdriver handle to see if egnine responds AT ALL, if so replace maf sensor, simple!

    Are you using a K&N air filter by chance? As they have been known for killing mass airflow sensors on GM vehicles.
