If you think you have a vacuum leak there's a trick I learned from an old carburetor mechanic that might help you find it. Get a can of spray carb cleaner and with the engine idling, spray it around the intake manifold mounting surfaces, throttle body, and vacuum lines going to the intake manifold - anywhere there could be a leak. If you spray it on a leak the engine idle speed will increase. Then just fix it.
