what should i set the CO to? on an exhaust analyser.

saff 4x4 dk greens stg3

i need to know what to set it to at idle, turned it down for the mot, as have idle problems.

also should i check it at another engine speed??

in theory if the engine is fully warmed, it shouldnt matter whether the iscv is plugged in. and does the throttle adjustment screw affect CO?

cheers guys
