Pejo 206 2002 model automatic gasoline + tube 1.4 engine. When my friends start the car in the morning or when the engine is very cold, after waiting for 1 minute at idle, when I change the gear from P to D, there is a knock on the car. When I gas it while it is, the sound of the car is different. It works a little loudly, it goes normal, there is no knock on gear shifts, but there is a strangeness in gas eating and sound. I stop the car and switch off the ignition. I'm running it again right away. The problem is solved. When I first switch from P to D, there is no knock.
I would appreciate if you could help what could be the reason.
