    My friend failed her auto emisions because her NOx is too high.

    She has a 1994 BMW, 2-door, non-sports car, that she bought used.
    She's not rich at all, and the potential cost of this repair is
    troublesome after a new transmission less than a year ago.

    What are some likely or low-cost things that might be wrong. The
    dealer had told her she might need a catalytic converter but that is
    ?? 3000 ?? dollars, or at least a lot.

    Would you try replacing the O2 sensor without any code that pointed to
    it? Sensors can give bad readings even though the reading is within
    the limits annd doesn't set a code, right?

    She's had plugs, cap, rotor, and wires done.

    If you are inclined to email me
    for some reason, remove NOPSAM :)
