Hi Folks, I have a problem with CO emissions at idle speed. CO = 3.5 (0.5 allowed) and HC 220 (200 allowed). Lambda 1.03 (OK).
Values at higher speeds are OK. It's a 96 with no proper OBD (and definitely my workshop does not have a connector).
Anybody experience with the problem or other suggestions? I thought perhaps the air flow indicator indicates too much air flow (than actual) at idling, possibly resulting in too rich mix?
