Nuru,
I'd suspect some deposits on the injectors causing them not to spray good at low rates. Would be worth trying some Chevron Techron diesel additive. I've used it twice in the life of my old Benz. Its symptoms were pinging at constant speed. Cleared it right up.
My 4010 will idle down to 1,000 and smooth. Think that's the specified idle speed on it after breakin. It's easy to reset.
