Just acquired a 1982 Mercedes 300CD with the OM617 turbo diesel. The PO, a friend, lives over 400 mi. away from me so I'm storing it at a friend's shop nearby for a few weeks until I can come back and hopefully drive it home. It was driven as recently as a year ago, and started only a few months ago. It started and pulled itself onto the trailer, and ran for about 30 mins. once I unloaded it. Of course, before making the trek home it will get an oil change and new fuel filters, etc., and a thorough mechanical inspection, but the one thing I'm puzzled and feel it may take me some time to sort out is that it seems very weak until the turbo spools - I'll take off and it accelerates very sluggishly until maybe 1/3 engine speed, then comes on hard and shoots up to the shift point. It does the same thing sitting in park, actuating the throttle by hand. Any suggestions to at least steer me in the right direction? I understand how diesel work but am not experienced with troubleshooting them.
