    back probe the dark blue wire.
    Hook up volt meter: Red lead to the backprobe and Black lead to a good clean ground.
    set up the meter so you can see it and read it while you are sitting in the car.
    Hop in the car, turn the key on but engine off. DON'T START IT!
    press the gas pedal to the floor and read the voltage.
    The WOT voltage should be more then 4 volts but less then 4.75 volts

    Isn't there and ODB-II reader that does this as well? I can't recall, and it's probably expensive anyways.
