[T3] Is it possible to do a smoke test to locate vaccum leaks?

I would expect it to be hard, but I've never tried it.

What most people do is use an unlit propane torch. If the propane gets 
sucked in it richens the mixture and the idle speed should change. I've never 
done that either, but it sounds more reasonable to me.

I would not expect either method to work well for small leaks.
