Scott,
Make the troubleshooting easy and simple. Before going crazy for these hard to find vacuum leaks, try the above suggestion first. Then proceed locating other most likely culprit. If the by-pass adjustment screw by the throttle body does not change or affect the idle speed, you have unmetered air going into the system.
