Mass airflow sensor would be a different fault code. Fault codes are specific to certain components and the areas of the vehicle they affect. Mass airflow sensor would be a different fault code. Fault codes are specific to certain components and the areas of the vehicle they affect.

No problem, but from what you describe I would go with the camshaft sensors. No problem, but from what you describe I would go with the camshaft sensors.

Just to add pulling battery leads is just a short time fix and could end up causing engine damage. If there is a faulty component the code will appear and the car will start to run rough again.
