.
did you try cleaning the throttle body, your intake could of suck something up there, and if it did you dont want it going any further.

sounds like a vacum leak to me, spray some TB or carb cleaner around the intake and listen for the engine to pick up a few RPMs.

Yeah, I've heard of the EGR spacers leaking coolant into the intake. Also a vacuum leak anywhere could cause this problem. Get a vacuum gauge and check the vacuum. Should be above 15 in Hg and it should get higher if you hold the rpms around 2500-3000 in neutral. Also look around and inside the throttle body area for debris or coolant.

Some throttle bodies make the whine and there really isnt anything you can do about it...what brand throttle body do you have?
