    change the lambda in the manifold.
    my readings were roughly the same when mine failed, flew through with a new number 1 lambda, the one in the manifold.

    A quick tip my saxo nearly failed it`s MOT on emissions it`s had a new CAT & lambda sensor,but was still overfueling.It turned out to be blocked injector/s so the garage put injector cleaner in the fuel tank & it passed.
