MK5 Zetec S (2001) Mass Air Flow Sensor issue? OBD P0172

Engine management light appeared on my 2001 MK5 Zetec S, the OBD reader reported P0172 (System Too Rich Bank 1) code. Sometimes when idle the revs fade away resulting in the engine cutting out. In the past a faulty Mass Air Flow Sensor caused the car to run rough, miss fire. I have tried another O2 sensor but the problem is still here, before I order another Mass Air Flow Sensor I just wondered what you guys thought? Also does anyone now the original part number for the Mass Air Flow Sensor?
