Check Engine Light Due to Failed MAF Sensor on Ford Expedition

The mass air flow sensor (MAF) may fail resulting in a rough engine idle, hesitation on acceleration, and/or engine stalling. The Check Engine Light may or may not illuminate. A failed mass air flow sensor will require replacement.

Rough idle and sometimes would experience intermitant hesitation at ignition and at acceleration. Sometimes would almost stall in traffic when pressing on the gas pedal or would be going 50 mph and the vehicle would begin to jerk as if it couldn't get enough gas and then all of a sudden accelerate.

Rough idle/check engine light/ told to clean with MAF spray - Auto Zone
2003 Ford Expedition- 5.4L V8166,000
Check engine (service engine soon)light with rough idle at times. I have been able to get the light to reset by disconnecting negative battery cable to see if it would come back. Took a week for it to show back up the first time. Went to Auto Zone and pulled code. 171 and 174 I think. Do not remember the numbers but the employee said Mass Air Flow Sensor (MAF). $100 for replacement. Had to order. In mean time several videos on you tube. Looks pretty easy and much cheaper than taking it to a shop.
