06 with 5 speed, when I push the clutch IN the idle drops to the point it almost (and sometimes it does) dies. Cleaned the intake, already replaced the MAF, replaced the clutch master cylinder and slave cylinder (did it before replacement, still does it). I'm at a loss, I've never seen this happen, it's always been the opposite (idle may wiggle a bit when you left OFF the clutch in neutral). Ideas??
