ERROR CODE 2-3-2

1989 Volvo 240

Hi,

my 89 Volvo 240 GLT keeps giving error code 2-3-2, "fuel system compensating for rich or lean mixture at idle, " according to the manual. The idling is affected, sometimes up to 1500 RPM. What are the possible causes of this problem, and how may they be fixed? It's a B 230F EFI engine. Any leads would be appreciated. Thanks!

Check and test the oxygen sensor/s, coolant temperature sensor, idle air control valve, throttle position sensor-also look for vacuum leak and check fuel pressure if its within specs-
