    When I told the mechanic at a local Chevy garage that I had problem with my TBI idle, only when it was cold out (25 degrees or lower), he said it might be my coolant temp sensor. Is there such a thing?

    It screws into the top of the intake right next to the hose outlet. Make sure you get the CTS for the computer, and not the sensor for the gauge.
