    Car failed NCT on emissions,
    It was only the low idle failed, high idle and all is good.
    What would be your thoughts on where to start?
    A good drive maybe ? Service ?

    Low idle CO is 0.81%, anything over 0.2% is a fail.
    High idle CO is 0.14% which is good as it is below 0.2%

    HC for low idle is 18 ppm,
    HC for high idle is 80 ppm

    Lambda 1, means car is running ok.

    Probably new cat time.
