Unstable rpm on a cold start GQv

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 ?

Hello there!
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,

I have never had this issue, but I would suspect dirty air/ air pressure sensors, dirty throttle body. You can clean those sensors and throttle body yourself to rule that out.

Could also be the ignition coils. Many people (mostly in the US) have problems with poor ignition coils (made by BERU)...
