[alfa] engine running rough when cold

[X194ME@xxxxxxx]

Hello there,

My Milano's engine has a  problem that it's getting worse with time, but only 
when the engine is cold.

As soon as you release the clutch the engine runs rough unless you run it at 
higher RPM's in other words is hard to get the car going without revving it up 
(but the engine is cold)... but after a couple of minutes runs very smooth, 
also sometimes the revs also drops down to 6-700 rpm.

I replaced the water temperature sensor and checked the auxiliary air 
regulator and it seems to be fine (opened while on the freezer and closed when warmed 
up) but I am not completely sure that is working at 100% 

I first noticed the rough running engine after I used some fuel injector 
cleaner and after that I read a section of the repair manual that says that the 
valves could be causing the problem, am I looking for the problem in the wrong 
place?

Three weeks ago I sent the injectors to get cleaned and replaced the fuel 
hoses but the engine keeps running rough when cold, I also noticed (lately) that 
gets worse when the outside temp gets colder 

Any comments or suggestions will be greatly appreciated, thank you.
