How can I determine if my MAF is bad? The car is a 99 pontiac bonneville engine is 3.8 no super charger. The car has been stalling occasionally and is doing it more often. The problem seems to happen after the car gets warmed to operating temp. But sometimes it idles rough as soon as it's started. The check engine light has come on and I took it to my local parts store to have it checked. The code read low imput to MAF. I have cleaned the sensor and the connectors. It seems to me that the sonsor may be going bad but has not completly gone bad. Any info would be helpful considering the sensor cost $168.00 and it would be a shame for my father to buy it and it end up not being the problem.
