Default You need a new MAF, something is unplugged or not grounded, the battery was disconnected or died...

That's a LOT going on.

As for the last two codes, it sounds like you either have a bad ground somewhere or that something on the top of your engine (if you have a 225) is unplugged.

Your throttle body is also upset, and if it's under warranty, I'd look into having it replaced or repaired.

Note: this is not especially expert advice, but I had similar problems, and that's what worked for me.
