I have the Peter Russek manual couldn't find a download but it's on e-bay, say "mercedes-benz 208D and variants" on the spine, but it's definitely on ebay. I too have a problem with my fuel injection system, seems when the engine gets hot the throttle doesn't shut off and it wants to run away with you - is this likely to be a degraded seal within the fuel injection system? My manual states the system is non serviceable... hmmmm....
