i never pat attention to the AC at WOT but i know the AC flywheel disengages at WOT so either that is what's happeneing or possibly vacuum loss is causing it to switch 'cuz that's what controls where the AC blows.

My Check vavle has a crack in it and i am assuming that is the problem. No the problem did not start with the drive shaft porntig. The guy who sold me the car over 3 years ago told me he had the drive shaft ported about two weeks after he bought it new.
