Re: Buzzing Noise
Is it a buzz or more of a suck type noise? If it only lasts a little while it sounds like the standard vacuum loss after engine shutdown - manifold vacuum pulls air through the ISC and around the throttle plate until pressure is equalised. An easy way to tell will be to suht down the engine with the throttle a little open and see if it still does it.
