Concussion in the first study

Good day, I just joined the peugeotturkey family. I just bought the car that will have a question. In the first study, it works jerkily, and there is no problem. Is there anyone who can help?

First of all, welcome to us. I wish you to use your vehicle without accident and good luck. the problem is probably caused by the engine and suspension wedges.

Thank you for your nice wishes and explanation
