leak

How about this? Buy a can of starting fluid with a nozzle. Spray around the suspected area and see if the eng. rpm increases.
 
If you are talking about a tb gasket leak, and what he mentioned doesn't work--then, while the engine is running try to tighten the tb bolts and see if the idle changes, even if it doesn't seal, at least you know what it is. Just be sure and not overtighten.
