Am I to assume that it is the monovalve, and if so, how do I diagnose it to make sure that is what it is?

See if you have a big black thing on the passenger side firewall with a lot of vacuum lines going into it...
otherwise known as the Evil vacuum servo. Thats your problem...as the 1980 300SD was a W116 chassis and never had a monovalve.
