Ok so it definately isnt AC related. I met someone today that says he thinks it's the pilot bearing. Have a listen and let me know what you think.

You will notice at the 39s mark or so my wife presses the gas and it goes away until the engine rests at idle again. I also had the clutch stick half way today while driving.
Now here is the thing, the car sat and cooled for a few hours and it went pretty much completely away?????
It goes from sounding like a diesel to back to normal and the only thing I can think of is that after some spirited driving it was worse so im assuming that is a symptom.
