    Hi all

    I have bad news, my 440 li 1.6 (B16F) failed its mot test today on
    emissions

    if failed the fast idle test where the %co2 should be below 0.3 my 440
    was at 1.8!!!!!!!!

    ok so i get the ecu codes, oppps, code reader on the car not working
    gggrrrr

    can anyone tell me how to test the lambda (oxygen) sensor with out the
    ecu codes before i replace it (£75 - yeah right).

    also what else can cause it to run rich, mass air flow??? how do i
    test that???

    Good news it that it passed on everything else, just needs emissions
    sorted.

    Thanks everyone

    Regards
