Sounds like you are trying to say it is leaking from the Upper Intake Plenum (Black piece)....They are made of plastic and are known to warp in the area you are saying the leak it coming from. Not a very expensive replacement, maybe $75 in parts for the Upper Intake and the gasket....Clean your throttle body while you have everything apart. An honest shop would charge you an hour to an hour and a half, it really doesn't take long at all.
