This afternoon I could tested it driving. And it feels awesome! The acceleration is soooo smooth, before it was rude, not linear. Now is so pleasant. Idle is perfect, it didn't hold at 2000 or any other revs, always going down to idle when shifthing gear. So idle issue finally solved!
I am so glad, reading your thread and getting to the part where you manage to fix your lovely car. Congratulations!
Can you please help me, as I'm not sure if I get it right. Was changing the O2 sensor the fix for your high rev idle? I am having the same issue with bad idle on my Punto, engine revs between 1500-2200 RPM more or less, and it does it totally random. One thing is for sure, on cold start it runs nice, when it gets hot the problem starts. Started a little time ago, at first was now and then, now it only runs as it should now and then, most of the time, when engine is hot, I do hav this high rev on idle problem, surging I think it's called.
