Is it possible to adjust the fuel mixture on the MAF for the m50 engine? Just had my mot today and the CO% was 0.671, which seems very lean to me? Or is that about average for the m50...?

Spec. is 0.7, so looks close enough to me! In any case, if this kind of thing is out, it indicates a fault somewhere which needs sorting, not introducing another fault (moving factory adjustments) to compensate.

That sounds close enough to me! I was brought up on minis and mk1 golfs mainly so adjusting the mixture has been the norm, but the maf is a sealed unit so you're probably right that I shouldn't start playing about with it.
Thanks Brian!
