Check all accessory mountings, belts, and pulleys for looseness. Check
the fan, could anything be coming in contact with the blades? Does it
vibrate while in neutral and car not moving w/the engine revving to 3K?
Does the buzz sound seem to eminate from the engine compartment or the
the tranny tunnel? Could be the alternator as suggested earlier, but
there is really not enough info to go on, and too many places to check
for looseness or wear. Has this vibration/buzz just started? Had it
awhile? Had it awhile, but not as bad and got worse?
