Recently I am noticing this muffled noise coming from the engine area. It is present at idle but goes away as soon as I start to accelerate. Come to a stop sign and there it is again. It is sort like a low muffled rumble. When I get out to try and locate it, it is even more difficult to make out because of the engine noise - so you can really hear it better sitting in the car.

I know this is vague, but does anyone have any thoughts?

Oh, this is on the '95 by the way.
