Fiesta MK7 cold start rough idle

Hi. 

I'm new to the forum and I hope I'm doing it right. 

I got problem with my wife's car. Fiesta MK7 1.25 petrol. On cold start revs are erratic, jump up and down, sometimes it feels like it's about to stall, it stabilise after a while but they stay high longer than they used to did. As soon as the engine reaches it's temperature the revs are stable and stay below 1000, also it starts normal every time.

I already cleaned throttle body, checked pipes connections, cleaned manifold temperature sensor, tested battery and disconnected for 15 min, started engine until warm, turned off and started again. No improvement.

Anything else I can do before taking it to the garage ?

Any help much appreciated.
