Not sure what "the problem" is, you didn't say?
MAF sensors can fail, it is just not a common problem.
If you got a CEL(check engine light) and a code number concerning MAF it usually means MAF Sensor IS WORKING, and computer is notifying driver of a data error issue when it compares other sensor readings.
Dirty MAF sensor can cause bucking and missing because computer is using wrong air/fuel mix to run the engine.
Corroded or broken wires can also cause MAF "codes".
