When Im at a stop and the car in gear I hear a humming noise coming from the engine compartment, give it a little gas or put into park and it goes away. The noise cant be heard from the outside the car with the hood up, only from inside the car. Anyone else come across this?

Do you have all wheel drive? I have something that seems very similar to yours. I have a 4.6L w/AWD. I don't know that I'd quite describe it as a "hum", but that works because I can't think of a better term just yet. It's almost like a low pitched and faint growl. I've wondered if it was part of the AWD system.

When you are stopped nothing in the AWD system is moving.
That engine has a known issue with a valve neaar the rear that is prone to noisy operation. Even though your noise is different, some searchs may be worthwhile.
The issue I describe only affects V6 equipped cars, but both RWD & AWD. If it happens when stopped, its not as likely to be transmission-related.
