Humming sound coming from engine

Humming sound coming from engine
2004 mustang gt , 149k miles automatic.
Took the car in the past to mechanics for this sound. Either the sound didnt occur while I was there(always happens when you try to show someone a problem) or they just couldnt tell the problem.
The best way to describe the sound coming from the engine is a type of humming. It sounds like a low version of Chewbaca's famous growl (star wars lol).
It either lasts for a short time or sometimes can last up to 8-10 seconds. It always goes away. Usually when the sound starts, I give the car a little gas and it will go away.
This usual happens in the first minute of driving my car and I come to a stop or in general when I come to stops. (If I remember right its done it while crusing with my foot off the gas, low mph).
Is it possible this is a bad idle air control valve? It has been doing it for a while now.
All inputs are appreciated. Thanks !

The air intake tract is referring to the IAC, Plenum/TB, and intake setup right?
I put the stock intake back so yes.
I notice that on idle, if my air conditiong is on, it does it a lot. Every other 30-45 seconds. (I changed my waterbump around 12,000 miles ago).
