Throttle body whistle at idle?

Does anybody elses do this? Mine whistles at idle and we just fired up my buddies new On3 car and his whistles too. Pretty annoying. Both cars started out not whistling and then started shortly after the first drive. Anyone know how to shut them up? Mine is a Summit brand 70mm throttle body, his is a BBK 70mm throttle body.

I wish it was that easy. My Megasquirt doesn't use the IAC, so mine is deleted.

Check for a vacuum leak elsewhere also. My upper-lower intake gasket was screaming like a supercharger when it had a leak.
