Exhaust gas emission

[kentish]

Hi to everyone.

Just got result of an emission test done on my car today at a friend place.

Here are the result.
Car has no calytic converter.

CO% Vol :5.53
HC ppm Vol h : 304
CO2 % vol : 11.8
O2 % vol : 0.53

Lambda 0.865
No PPM vol : 75

Car is a 540iA 1994 withou calytic converters. None were fitted to the car. Its South African model.

what you guys think of that? my friend told me that am running a bit rich with 0.865 Lamda and the CO& is out of range completely because no catalytic converters are present.

Could it be spark plug giving that rich lambda

Thanks
