    Hi Chaps
    The first thing we did on this car was to replace the O2 sensor, but that had no effect same fault.
    So i went back to the original O2 sensor.
    After fitting a new Air mass meter it gave us a very rich mixture after 10 mins and set p0170 rich exh.O2 sensor stuck at 900mv. This morning i decided to have a last try and went back to the new O2 sensor.This was the final cure O2 sensors are now switching perfect, emissions are bang on the money, car has now been running for three hours and has never set a fuel trim fault.

    I imagine that the original air mass meter had run the car lean for such a long time it had probably damaged the original O2 sensor.

    Vauxhall information is incorrect about the fuel pressure their tech info states 3.8 bar unregulated. but it is actually 3 bar unregulated and 2.4 regulated. Vauxhall technical finally agree with me on this. But say the German production side state 3.8 bar.

    Many thanks for all the replies
    I'm having a weekend off.
    Regards
    Dave
