Could be coolant temperature sensor faulty.
When it fails the ECU uses a sort of 'mid range' figure to keep running but could result in under fueling when the engine is cold and over fueling when the engine is hot.

What engine is it ?.

So now it looks like dirty or faulty idle control valve, see here:-

Anything else you think we should know ?.

Well that suggestion is just plain wrong!, the ECU varies the amount fuel based on readings it gets from the sensors.

Did you you check the ICV?

Mine did this but cleaning and following the published "reset" procedures didn't help, but reseting it via testbook cured the poor starting and cold idle.
