good day everyone.
My vehicle is 2005 model 307 1.6 otm.
I have a problem like this. When I take my foot out of the gas while going downhill with my vehicle, the car seems to be eating chopped gas and fluctuating at the tachometer. There is no problem with idling. There is no problem when pressing the gas or I do not notice, but it does this from time to time when I take my foot out of the gas. I have tried both in gasoline and gas, both do. If someone is faced with such a situation, I would be glad if they help.
Thanks

I have 206 1.6 110hp vehicles. I think it must be the same as your engine
These have electronic throat butterfly
First, have a nice clean throat butterfly, then connect it to the PC and adapt it.
If there is no improvement, the last possibility is to replace the complete throat butterfly. I had to do it :)

Is it necessary to adapt when the throat butterfly changes?

Yes, it is necessary for electronic butterflies. A simple process takes 5 minutes or so.

It was a little late, but the problem resolved after clearing the throat butterfly.
Even without adaptation and removal, cleaning with a spray and air gun.
There is no problem for now.

Get well soon. No need for adaptation when the throat butterfly is cleaned without disconnecting the socket

I do not know if my master problem is still going on, but there was a fluctuation of idling on the way where he was standing, even the heating is going the same way, he was coming, I thought that he had a new lpg, but he was doing it on the gasoline. My vehicle remained in the industry for 4 days, they tried everything, they changed all imaginable parts, there was a super 14 - 14.5 when the alternator was measured with the device, but when we connected it to the computer, we understood that when the heater was switched on, the alternator income was 11, 13.5 when the load was on. Then zero original charging dynamo was installed and my problem was solved completely. Part price 1100 pounds labor, 300 pounds in total I gave 1400 TL in total, my soul was saved.
