Question 2009 2dr auto hatch with check engine light/P0101 code

Car has 265k miles and runs like a champ with all regular maintence. I turned it on and it ran in the driveway for like 2 minutes yesterday - when I hopped in the Check Engine light was on.

The car runs fine and when I stopped by autozone that was he code they gave me. Per their paperwork it's either a dirty MAF, a loose cable, or the computer has gone bad... would the car even be running if the computer went bad?

I've had an aftermarket K&N air filter/ typhoon intake on their for about 80k miles and cleaned it a few times with no issue. After the code I cleaned the air filter, reseated the plug on the MAF, checked all the connections, and, probably erroneously, disconnected the negative terminal as I recall this resets the computer. The check engine light went away but I suspect it will come back once everything recalibrates. Car was a little rough after the reset but has since smoothed out and drive fine on the way to work.

If the code comes back any recommendations on how to clean the MAF? Autozone sells them for like $70... but I didn't want to swap stuff out and pay $70 until I poked around a little bit.

Any suggestions?
