    Not a great start to my Sunday ! Skoda Fabia 1.2 petrol failed on high idle test and I'm wondering where to start.
    Details:low idle co 0.20 hc 16 (pass)
    High idle co 0.61 hc 11 (fail)
    Lambda 0.99 (pass)

    History:New cat fitted 6 months ago after injector failure.
    Eml came on again 2 weeks ago,new lambda sensor fitted.

    No engine lights or fault codes showing

    Was it a genuine cat?

    With low HC and that CO reading it would suggest cat.
    Assuming that the engine is running ok.
