206 cycle problems, please help friends ..

My car is 2000 model 206 automatic gear. For the first time I encounter this problem for the first day. My car is running under the speed that should work normally at idle. Especially in the city, it started to stop sometimes during the pauses, under other revolutions that should be in other gears. There was no change, then I gave it a gas additive, but I still have no change. I am waiting for your urgent help, friends, where is the problem? Thank you from now..

Hello my friend, I think the problem is important, bless you, show it to a service on the way or the best ...

Thank you very much for your answer, do you have any problems or have any ideas in the forum?

How many hours do you idle? can be from the idle regulator

It falls between 2-3, then collects a little, 6 also stays, if the vehicle is not too hot, it stops, I went to the 2nd service today, they said it could be from the idle engine, the service I went to before said the thermostat and the two clients on it were defective and need to change. I will change the customers with the thermostat this weekend. Thank you for the answer.

It can also be from the oxygen sensor.

Idle engine was probably the same problem in the 2000 2000 xr auto. idling engine changed no problem now

thank you guys, I will try it in order for your answers.
