There's a similar post up by mr mugen (http://http://www.gtr.co.uk/forum/126662-failed-emissions-co-help-please.html) but his problem is slightly different, so I didn't want to hijack his thread.
I failed to get my GTR on the road over here in Luxembourg cause the emissions didn't meet the requirements. Now, today I went to a garage to get the numbers and this is what it says:
It's been measured while idling. I'm a bit confused since I don't know how the lambda can be that high (as is the oxygen). Wouldn't that mean that it's running super lean or shouldn't it even stall? The thing is, the engine is running really good and since it's almost completely stock (apart from an Apexi induction kit and exhaust), I can't see how this is possible. Now, what I'm gonna do tomorrow is check the sparks to get already an idea if it's running too lean, but what else could cause this?
Any ideas?
