spark plugs? can you confirm that this is a gasoline/petrol delica and not a diesel? (diesels don't have spark plugs, and gasoline engines rarely put out black soot or smoke, usually grey or blue)

could you also clarify what exactly you mean by "spark plugs keep choking up black"

As for the black exhaust on start up, many possible causes, if it is just soot and not black smoke, I would recommend a good diesel purge, possibly simply a long highway run, or better yet a chemial purge. could also be gummed up EGR, misadjusted injection pump, gummed up injectors, clogged air filter, or several other issues.

im gonna assume by spark plug your referring to glow plugs (not the same thing). usually black smoke and rough starts can be drawn back to one or more burnt out glow plugs.
