Idles rough, but runs good when giving it gas.

I second the vacuum leak theory. At idle the intake manifold is at a high vacuum resulting in significant air entering through the leak, leaning out the mixture. As you open the throttle, vacuum drops and less air enters via the leak, and the mixture richens.
