When you put it in neutral the load comes of the engine and the revs raise a little thats why the ratting stops. If your mounts look good I wouldn't worry about it.
The Idle Air Control sensor decides how much air to let in to idle the engine when the throttle is closed. If there was an issure with that you'd most likely get a SES light.
