Hey!
I have 97 model of Alfa Romeo 156 2.0L twin spark!
There is a problem when the Engine is Cold, after drivin the car for like 3-4 mintues it the engine sometimes starts to misrun, it goes from 400 to 1200 rpm. After a minute or to its stops again.
Can it be that its the inner airbark(wich is broken) can be cousing this or is it the headpack that is broken?
Plz help!

Could be the air mass flow meter causing it to idle irratically.
Does it misfire at all? if so then yes the coilpack could be breaking down as you predicted or it could just be a duff spark plug causing the misfire. It would need to be misfiring to be either of these though.
