Sounds to me like you have an intake gasket or a vac line leaking. Get a can of brake cleaner or starting fluid (brake cleaner is preferred) and spray it around the engine with it running at idle and listen for the engine to rev up. if you spray is near the intake and it revs up, time for new gaskets. If you spray it away from the intake, near a line or something, and it revs, start looking around there for a broken line. if you fined one, it can be easily repaired with a 2 inch section of rubber tubing about the same diameter. just slip the line into the tubing and it should work just fine.
