My 4/4 with a 1.8 Duratec engine started playing up this morning caughing and sputtering after stopping to get some fuel the engine management light came on but the car quickly sorted itself out. On investigation i came up with the error code PO403 (exhaust gas recirculation control unit)

Any suggestions on resolving the problem greatfully received
