Before suspecting an air mass meter I would check very carefully for vacuum leaks - even small ones can trigger such a symptom. Also verify that fuel pressure is correct, not low, and check for anything else that might weaken the fuel to air ratio.

Air mass meters sometimes burn out in which case the car will not run unless the meter is disconnected. There are fewer reports of marginal air mass meters, of the Bosch design used on Volvo. They are self-cleaning. Not so for some US cars where the non-Bosch meter can become dirty.
