If this sensor has a defect, could it cause misfire and lag of power then the engine is cold?
Yep! You support my own theory Ziggy. I have had problems with our Punto, but especially when it is cold weather/ winther time. I know plugs, leads, coil are ok and i have just changed the generator and battery. My next guess was the temperature sensor. When the engine is warmed up after a few miles, it runs perfect, regardles of the weather.
hmmmmm
that doesn't sound sensor like to me....
But there cheap here (£5 if you have the unscrew type)
i'd be tempted todo a compression test to see what the compression is cold

Rough running at low temperatures can be an early sign of HG issue. Alternatively, how old are the plug leads? Reliable life of OE ones is about 4 years. Some of the cheapo replacement ones less than that.
Well time for an up date. I never got to test the commpression.
I spoke to a FIAT mecanic and he said " Søren the 1,2 16v is hyper sensitive if the plugs and leads are not original FIAT parts. And when you change the plugs, the threads on the plugs, has to be absolutly clean! You must ONLY tighten he plugs with 1,8 kg/ 17,5 Newton! NO more than that!!"
So I did what he told me to do and the car runs perfectly now!??
The "old" plugs and leads was from NGK but that was not good enough!
