An easy test you can do yourself is to take some starting fluid and spray it around the engine and vacuum hoses (also along the intake manifold) with the engine running. See if the RPM's pick up. If they do then you've found the problem.

If that doesn't do it then your best bet is to take it to a repair shop that has a "smoke machine". This machine will introduce smoke into the system and will show any leaks. This is by far the best and fastest (and inexpensive) way to find a leak.
