    It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. My first thought would be to look for vacuum leaks around the intake manifold and air induction boot. The Bosch K-jetronic system on that car is sensitive to water in the fuel, passage ways in the mechanical fuel system can easily get damaged internally. Although the type of injection system use on that car were used by other Mercedes, VW, Audi, Peugeot and Volvo a lot of younger fellows aren't used to working on K-jetronic fuel systems, best to find an independent Mercedes shop in your area familiar with those cars. Even younger guys at the dealership have never worked on these fuel systems.
