Wave an unlit propane torch around all the joints (intake, EGR tube, etc etc) and listen for a shift in the idle. That'll at least point you in the direction of your leak (if you indeed have one).

Ya know we tried this on Luke's car. Even went as far as pulling the PCV valve and shoved the propane torch on full right up to the PCV and the idle would not change. Turned out he did not actually have a vacuum leak, it was just a bad IAC connection, but I really thought this trick would work.
