Had my emssions checked today and it just passed but just it seems to be the co on the fast idle thats high the limit is 0.200% and mine was on 0.198% only just, they checked it again and again it was the fast idle where is registered 0.199%

The natural idle was fine limit is 0.20% and the actual result was 0.00% nothing, just wondering why its just getting through the fast idle test on co all otheres are fine, just worried something may be failing when its test time in the next few weeks.
