When the weather is warm (50+) I hear a sound sort of like somebody blowing their nose really loud and it vibrates, from the intake area. I only hear this sound about 2 seconds after shutting off the engine. When it is cold out the sound is almost gone except for a sucking sound that is barely noticeable.

I have heard when the IAC goes bad it makes a fog horn sound. I understand that to be while the engine is running.

Should be the IAC here as well, it can be typically heard as a fog horn or moaning sound when it begins to act up or fail, but can also vary in the type of sound it emits. Sometimes cleaning it can help, but it's a fairly inexpensive part and an easy one to DIY replace.

My vote's on the IAC also. Mine was making a weird noise too (search "doot" in these forums) and replacing the IAC finally did the trick.
