Why not try the throttle body cleaning, if you replaced the MAF 11 months ago.
I've been reading a lot of posts with the idle hunting problem and when everyone suggests cleaning the throttle body it resolves the problem.

I'm no expert on the subject, but I have read enough posts in this forum about idle hunting.

I've had hunting idle and CEL some time back. cleaning the MAF, but more so cleaning the throttle body, as many members recommend cleared the problem.
two to three years later, 1128 and 1130 but stable idle, replaced MAF and no more 1128/1130 combo. Sorry, no help, just an intro to what I've experienced.
