ok had my car sitting for a couple months...(i have been starting it 3-4 time s a month)about a week ago i was starting it and this loud and i mean loud huming coming from the engine....at the time it was to loud to pin point it...since i drove it around (maybe 10miles) it had gotten softer and i can hear it comin from the intake. i tightened everything down and still no change. its not constant....but seem to be comin from my filter area.

any ideas.????

thanks
