If you don't have access to one, either do a very close visual inspection of ALL vacuum lines, use propane around the intake manifold, or vacuum gauge on all lines.

You can use brake cleaner or a can of quick start. Get 2-3 cans and spray all lines with vehicle running. Listen to the idle, when it drops at a certain area you're spaying at, you found to leak. The other way is by sound sometimes, vac leaks are usually noisy.
Soap Bubbles, Vacuum, Bubbles? Its sucks not blows so that wont work. Start engine, spray some WD-40 around suspected area(s), if engine idle changes then you have found your leak...
