It does sound like a vacuum leak. Have you checked all of the vacuum hoses and the base gasket on the throttle body? Also, I never heard of using WD40 to check for a leak. Most people use starting fluid. However, it can catch fire if you hit the wrong place. If you try that, keep a fire extinguisher near by.

Let me know what you find.
