Black smoke and shake

At 206 hdi there is a drop in revs during take-offs and gear changes. From the moment I first started the car, it is constantly blowing black smoke. When the speed reaches 80-90km, the vehicle is shaken. What are the causes and solutions for these problems now?

If the reason for the blackening is the injectors need to be cleaned, if the shaking is shaking and the gear knob is shaking hard, the room is from the axles. most likely from the right axle. Room exits will be found and changed. samet2461 2013-04-07 10:45:59

If the tires are too old from the tires, the car also makes humming and trembling or does as the friend says. If it is applying pressure to the brake, the discs are crooked.
