Rough idle when engine is warm with automatic transmission in park. Smooths out when transmission is shifted into either reverse or drive. Seems to be vacuum related. Any advise as to how to repair?

Check all vacuum lines for splitting disconnected etc. Then use choke spary around intake to see if rpm changes if it does you'lve found the leak.
