The only reason i target 14.7 (or 14's in general) at idle and low load is for emissions and a happy MOT man

theres no denying that a rich idle is a smooth one.

Idle isnt tested on then MOT is it? its normally just tested at 3000rpm isnt it?
Edit - actually forget that it was 3.5 CO at idle on older cars I remember now, but even at 12 or 13 it will still manage that anyway.
