    this may help some one. I have a 92 sl2 and the mileage had been down for
    some time. There never was any code set to tell there to start. After many
    hours of head scratching I checked the coolent temp sensor. It was not in
    the 20 to 50 ohm range when warm. I set it in a cup of boiling water and rad
    with a digital meter. It read abput 1200 ohms. This caused the system to run
    in the open look as it was warming up all the time. Thus more fuel used. I
    changed the sensor and all is well. you can disconnect the sensor and hook
    up a resistor of about 100 ohms and watch the ox sensor to get back to its
    lean state.
