High G's and transitions make me think of loose wiring connections/shorting as the computer is going into limp mode.

It also makes me think of the crazyness I had going on with my MAF. It was intermittent in nature.

I took the MAF cleaner to it and the wire harness/plug connectors and that fixed it up.

I also pulled the filter and inside the filtered side of airbox in the drain I found bits of loose paper that looked like a parts number label, maybe from the filter element?

Since I cleaned all that out all the codes went away and it runs like a champ.

Since the computer is only responding to inputs that don't register as sensor faults, yet drastic enough for limp mode, but intermittent with the G's, I would also suspect the connections/shorting somewhere.
