I don't know much about GDI engines
Heard talk about intake valve getting dirty with carbon build up

On other cars, the coolant temp sensor can feed bad information to ECU
So ECU doesn't know what amount of fuel is correct when cold
It can be trying to run at normal operating temps when cold???

Idle air control valve, or idle speed control??
What about a vacuum leak???
Cold there is a leak?? Then after warms up, thing expand to fill gap????
Does a GDI engine even have anything like these??
