Ok, some of these engines did use a vacuum hose at that fitting. If there is one, it will be located on the back side of the engine near the 3 ignition coils. It will have a 90 rubber elbow on the end of it. It will be a small diameter hard plastic line.
If you don't see one of these lines, place a rubber cap over the port. Either way, it should not cause the vehicle to stall out. You may need to clean the inside of the throttle body to remove any carbon deposits to give the vehicle the proper airflow.
