David,
congrats and welcome to the diesel club. I have a '85 300D and I absolutely love it. One thing that another member recommended to me was to add a bottle of Red Line Diesel Fuel Catalyst to your tank before filling up. Then add a little every time you fill up for maintenance. It seems to make it run alot smoother. You should be able to pick it up at
any auto parts store (Pepboys if you have them up there)
Happy motoring.
