There is a shop locally that has a MAF sensor, I'm tempted to take a shot in the dark and replace it. The car has 120,000 miles and its on its original MAF sensor.

MAF's are not cheap, and rarely cause flashing CEL's, in fact the car can run just fine with it unplugged; I would not be throwing parts at the car until you confirm what exactly is causing the codes.

I tried unplugging mine to see if it would make a difference and the car wouldn't even start.

I think your cams have jumped timing. Big issues, good luck, don't plan a vacation any time soon.

THen why would it run fine before disconnecting the battery?

Very unusual as the MAF does very little below about 2,500 to 3,000 RPM.........
