Clean your throttle body and Idle control valve, they are probaly full or carbon. remove the air filter hose from the top of the intake, that is your throttle body. get some throttle body cleaner from any auto parts store and spray tll it's clean. If it still idles bad, you might have a vacuum leak. Check all the hoses and listen for hissing while the engine is running.
