standard test failed

I understand that it only requires standard test but reading was
Eight point nine and lambda was not showing on the scale.
So over fuelling by miles no error lights nice stable idle
I assume it is the lambda sensor sending incorrect readings
Will get new sensor tomorrow and fit have just ordered consult cable to diagnose ECU and have borrowed single gas tester for a day hopefully to sort it out but if any one has had a similar problem before any hints would be helpful

:chairshot
Also dose any one have or know of a cheap gas tester single gas is ok CO%.

i have got a couple of stageas through sva test and mot no problems at all.
Should be no problems as standard rb25det engine . The problems not because it is a stagea ,

Try testing the emmisions with fuel cap removed, incase it has a breather blocked.
