Does anyone know how I can get the stored error codes from the\ndiognostic test point of my Volvo 440. The ECU is a seimans type and\nthe fuel system is a B16F. The car has been idling roughly over the\npast 9 months. While cold the idling is quite rough. After this the\nidling speed settles at about 1000RPM. This is set by the constant\nidling system. However, when the throttle is pumped the revs fall to\nabout 600RPM before picking up to 1000RPM. It has recently been cutting\nout. When this happens, it will not restart until at least an hour\nlater. There may be a temperature issue and I'd like to see if the\nerror codes will give me any clues.\n\nMaurice.
