For your question:

Have you done anything with your timing lately? If your timing is off that will cause low vacuum at idle.

That's hilarious.

Now for the question. You should see somewhere in the area of ~15in/hg at an idle. Make sure the line on your vacuum guage isn't pinched. With 3in/hg I'd expect the car to idle like crap.
