My 85 300D with 284,000 on it smokes worse than normal when first started and idles very rough. I run mobil 1 fluids, keep good filters and such, just had the valves adjusted 5,000 miles ago etc.

I also replaced the injectors a few thousand miles ago. Sometimes it even idles very rough and smokes after the engine is warm.

Could this be an injector pump issue?

I'm pretty new with these cars (but learning), so any suggestions would be helpful.

My 83 300CD runs better than any 3.0 I've ever driven.

Thanks.
