Hey all after turning off my engine i can hear this buzzing noise coming from the engine somewhere? Its noise is coming from the ISC area. Is this a sign of a vaccum leak?

thanks

How long does it last? I noticed a while ago that mine did it if the key was on, after taking it off and cleaning it the noise stopped. It was definitely an electrical buzzing noise BTW

if i turn off the engine it buzzes for about 1-2 seconds?

i dont know if its electrical or a vacuum leak. But my friend from what he saw said it was a vacuum leak? He didnt look for long tho.

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.
