206 Self-gas delivery problem (SOLVED)

hi firstly.
I have 206 vehicles with the 2000 model 1.4 gasoline and I have had the problem of self-gasing for a few weeks.
the problem is like this.
When the car is driving, it gases on its own and the gas pedal is pulled down as much as it gives.
Shaking is experienced as the car does the same problem while driving.
the same problem occurs when I stop at the lights or wear it in vain.
very rarely it stops itself.
yesterday we cleaned the throat butterfly and idling sensor, but today it did the same problem.
I wonder what's wrong, guys?

We took it to the mechanic, said from the idle valve, said, let's replace it. so we figured out that it wasn't a good deal for the mechanics. (Not valid for everyone, of course)

Did you look at the idle valve engine, this happened almost everyone here, it happened to me.

we removed it and cleaned it, but I don't know if it has a malfunction.
