Hey lately i noticed that on a cold start the engine rpm is unstable until the engine warm up . There are no errors on the screen.
What could be the problem ?
I'm from Portugal and i have the same problem with my Giu 1.6 120cv (June 2016).
I still do not know what to do..
Only do this at cold start... and stays like that for about 15~30sec
Thanks in advance,
