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.
