My 1984 300D, which I loaned to a child, sat for two years down in Florida without being properly stored. The car has only 94,000 miles. When I went to retyrieve it, the engine started but is running very rough. I suspect that the injectors are gummed up from the old fuel in them whenj it was shut off. My question is whether there is some sort of solvent that I could run through the engine that woulkd free them up. I don't really want to have to remove the injectors.
