    Hi Folks,


    Previous reading

    low idle 0.02 pass
    lambda 0.99 pass
    high idle 0.45 fail

    Now I have cleared nct with no problems

    low idle 0.15 pass
    lambda 1.01 pass
    high idle 0.17 pass


    Solutions used

    1. Diptane with reide of 20 min on fourth gear before nct
    2.Change of flexi pipe


    Usually i was told if flexi exhaust is worn or broken nct guy tell you.But they did not tell me.My mechanic found it out.So in near if any fails on emission please check flexi pipe by giving a glance at it instead of wasting money putting cat, o2 and lambda sensor.Start with this its pretty easy.


    Hope this helps anyone failing on high idle co emisson.

    Thanks
