· A bad MAF sensor can cause too much fuel to be left in the combustion chamber, creating untimed detonations. You’ll experience this as poor drivability such as hesitations or sudden jerking motions, particularly during acceleration. This could happen while speeding up on the highway onramp or cruising down a city street.
