  1. 3.0 v6 throttle reset

    Alfa GTV & 916 Spider
    Hi guys my V6 ph 2 failed on the idle emissions, the car runs fine but something is obviously amiss. It has the fly-by-wire unit and I'm wondering if the unit needs a reset or whether the butterfly is not operating correctly and could be over-fueling. High rev emissions were fine. Any ideas...

    Alfa 159, Brera & 946 Spider

    Alfa Giulietta
    Hi All Had the engine light come on and after reading the codes (MES), I had the above come up. I've cleared it but obviously I need to address the issue. Looking on the 147 GTA forum this was fixed by unplugging a clip, cleaning it and then plugging back in. Does anyone know if this is a...

    Alfa GTV & 916 Spider
    Since I have my car it never behaved right.

    Tuning & Upgrades
    Hi all! I'm wondering what aftermarket, or upgraded, throttle bodies y'all have fitted on TwinSpark engines?

    I have a 210 brera diesel that smokes quite badly when under hard acceleration/ full throttle. .
