Bummer. At least it will probably be much easier/quicker to remove the intake manifold the second time, now that you're aware of all the little things that need to be disconnected.

As horrible as it sounds, I really hope your problem is a simple leak at one of those connections. It will be a pain to remove the intake manifold, but at least it will be an easy positive ID of the source of the problem, and should be easily solved by re-tightening the problem connection and/or re-applying new thread seal tape (make sure you wrap in the correct direction).
