Putz,
TH is when you're accelerating...push in the clutch to shift, let off the gas..and the revs kinda hang up there before slowly coming down. Kinda like an 80's smog car.
Moosing...is an incredibly irritating and loud sound that is very apparent with an open filter. You're accelerating...everything sounds cool with your open filter, and as soon as you let off the gas...this moosing or moaning at just the right pitch which is irritating as hell comes out loud. Also happens when the AC or defrost gets turned on.
The TH fix will alleviate both in one fell swoop. And at <$1..its cheaper than a new AIC (or is it IAC)....
