Okay, let's start a post for finding and fixing vacuum leaks.

There's a good chance I have a vacuum leak in 2072 that I can't find, so what's step 1?

Is there an auto parts store that would rent a smoke tester? Or should I just spray carb cleaner, looking for the leaks? Is there a way to verify the routing of the vacuum lines that go under the intake manifold without fully removing it?

As this post goes on, I'll edit this post with more info and suggestions, so that it will end up as a good resource for others.

Two more options, which I have better luck with, are a small propane bottle or better yet a trickle of water...you can hear the engine change with either. With water, you can also hear the first and last "slurp" when you hit the right spot.
