Replaced my IMG about 3 weeks ago, about a week ago I start getting a whistling sound from under the hood, cant find any vaccuum leaks, thinking it may be the IMG........only thing is that the whistle goes away under throttle, its only there at idle??? any ideas??

Makes sense that it goes away under throttle as you have high vacuum at idle, less so under throttle. My vote is still a vacuum leak.
