Most likely just cleaning the MAF will fix you issues. There is a special cleaner for doing this and make sure not to touch any of the sensors internal parts with your fingers.

I've had those codes as well, and most of the time it is a vaccum leak. Check all your hoses for cracks and collapsed hoses. Best to run the car and open the hood, and listen for hissing, move some hoses around to help. Un-metered air from the MAF is being detected. Do this before you spend big money on a new MAF.
