Assuming its the magneti marrelli system that was on my 2.0 405, it could be the idle stepper motor or (in the case of my 405) the throttle position sensor. Try turning the ignition on (key position II) and waiting for a minute before starting. The engine mangagement re-learns the idle point of the throttle sensor. If the idle is then Ok, it is more likely the throtttle position sensor.
