CEL came on this morning on the way to work...had it checked at Autozone tonight. Any thoughts on what might have caused this or what I can do to fix it?

You must be running more then stock boost. So you MAF was reading a higher then spec 5.0 volts
 
Actually 4.9v or higher can/ will set the code.

Best bet is to check for loose connections at the maf. If you don't find anything bring it to the dealer.
