I encountered the same issues (and same P1126 code IIRC) with my 2.5L this past summer and tried many of the same steps you tried like cleaning, disconnecting the MAF, checking for vacuum leaks, O2 etc.
I know you said you checked the intake already, but its worth checking again between the airbox and the screen just downstream of the MAF (assuming the S's intake also has a screen).
FWIW, the culprit on my car turned out to be a clear piece of plastic wrapper caught inside the intake on the screen inside the intake tube just downstream of the MAF. I'd checked the intake previously but I didn't find it at first since the plastic was clear and not very large (maybe 1" -1.5" square) and it might've been clung to the side of the intake.
