Good morning, I have a problem with the acceleration of my twingo since in rest mode it accelerates and decelerates continuously, they have told me that it is the IAC valve, in any case I would like to know where it is located and how to do maintenance in case it is repairable
If but you should be careful the oscillations in relief, they are mainly the fault of the IAC but it may be failing another component, this valve goes in the admission body can take it very carefully and clean it, it would also be good that you would clean the body so that there are no Inpurate in the system.
