 ;D ;D ;D

my initial thought was air leak. spray the top end in key spots with carb cleaner and listen for the idle to change

Would have thought an air leak would cause a rough idle if its enough to be heard easily

If it appears to come from beneath the car, get beneath the (pit, lift, axle stands) and listen there.

try pinching the idle control valve hose..slowley until the car almost stalls, i bet that stops the noise, you will hear the difference.
mine started doing this when the coil (DIS) pack started playing up. the best i could figure was the ecu was adjusting the idle to compensate for the rough running caused by the coil

Also noticed today when it starts doing it if you bring the revs up it stops or if you blip it the noise changes slightly as it returns to idle ? Very strange just can't seem to pin point the noise  :'(
