IIRC, the idle air control motor will start whistling under some condition and I have totally forgotten why. It's been forever since I've seen this. Seen it happen on the crown Vic's with the 4.6 also. If you haven't resolved it by Monday shoot me an email at sixgun 452 at yahoo dot com and remind me and I'll dig around and see what I can come up with. Also, just for grins, check your PCV hoses and fresh air intake duct work for vacuum leaks. It's very common for Ford vacuum hoses to deteriorate and suck holes in them and also very common for folks to leave the PCV vent side hose that plugs into the fresh air intake hose off.
