Technical Punto mk2b, bad idle.

Will have to try.
Today I looked under the hood, but I still haven't figured out how to get to the temperature sensor connector.

i am sorry i only just noticed you asking about the position of the sensor. It is just in front of and below the throttle........good to know you have the car running now

I'm having a similar problem.

I continue to research and purchase parts.

maybe it will be useful to you.

If you haven't removed it before, I added an image of the temperature sensor socket.

I found interesting information, I haven't checked it myself yet, but the ECU had the same problem as in the photo.
As soon as I have free time, I will check this wiring harness right away.

I had a similar idle problem before.
The problem I had been struggling with for weeks finally turned out to be a broken cable.

But when the fault light is not on, the parameters are too wide.
