    Hi, just wanted to post a Saturn fix that had me chasing my tail for a
    while. My 1999 Satutn SL1 would lose power when the engine would reach
    operating temprature. I would NOT get a Check Engine or Service Soon
    light. I did the usual like changing plugs and filters with no luck. I
    did some research using my Haynes book and found the the the Tem sensor
    can malfunction without giving a Check Engine. The Emissions looks for
    a signal from the Temp sensoe along with the O2 sensor to regulate fuel
    mixture. I went to my Saturn dealer to by the part and luckily ran into
    a Mechanic on break. Asked if he could give me a tip and explained the
    above. He imediately said it was my Temp Sensor or the Temp Sensor
    connector. He said that after time it can weep a little antfreeze and
    contaminate the connection. I bought both parts and it fixed it. So
    remember... No power when warm and no Service Soon light meand Temp
    Sensor. $45 with tax.
