A great way to find vacuum leaks is with a spray bottle of starting fluid. If you spray it around the various vacuum sources and air ducts a vacuum leak will show up as a change in idle speed. You can also use something non-flammable like brake cleaner. WD-40 works too, but its still flammable and messy.
