    this van has high co at idle about 8% it has no cat and no o2 sensor .bit of a rare one ,has anybody any info as to where or if the co is adjustable?or could it be that the ecu has to be suitably programmed? cannot see any adjustment screw or potentiometer anywhere,the only thing i have found is a two pin connector apparently coming out of the wiring loom near the inlet manifold.no fault codes on the van and my snap on scanner does not mention co adjustment.any help much appreciated.

    Graham.
