W203 C200 Works restlessly, small black smoke coming out of the exhaust at regular in

If anyone has struggled with this, and how did they resolve it?
It accelerates OK on hilly terrain, when it gets out of gear it works restlessly. It runs like it's going to shut off (it never shuts off) and I can see black smoke coming out of the exhaust at regular intervals, strong black smoke also appears if I accelerate it to a higher number of engine revolutions.

Plugged into the computer, it doesn't show any error.

Model W203, 2003, C200 CDI
