Answers :

Your problem is typical to a vacuum leak. Check all of the vacuum lines connected to the engine for proper connection, and make sure there are no cracked vacuum lines. If you don't see any vacuum hose problems you will need to check the intake for leaks. The easiest way to do this is to take a spray bottle full of water and spray it around the intake and intake hoses with the engine running. If there is a change in engine RPM's while spraying with water, inspect area for the source of the leak.
