    Idle's too high

    Hi guys....can anyone tell me if there is a way to turn the idle down on a 93 Camaro with a 3.4L V6..? Mine sits at almost 2000 and goes as high as 3000 when its warming up in the driveway and stepping on the gas does not bring it down.When I put it in gear at this high idle the back wheels wanna spin free.Even after shes warm it still idles at about 1200-1500 and I feel thats way too high. Any help would be greatly appreciated.

    No, there is no way to change the idle properly.

    Sounds like you may have a malfunctioning TPS or IAC sensor.
    3.4/3500 Twin Turbo almost complete
    I have CNC machines, contact me if you need something. 3500 top ends available.

    Thanx for your response....is what you're talking about called the "Air Charge Temperature Sensor"..? If so thats only $20 ...pretty inexpensive part but I need real bad.

    Thnx again

    +1 for the tps or iac but have you tried taking off your throttle body cable an check to see if thats mess things up? i would try to start it with the cable off and see if it will drop your R's since your not getting a SES light

    IAC = Idle Air control

    TPS = Throttle Position Sensor


    Theer should be no change if the throttle cable is removed. The IAC allows air into the engine to regulate idle via a variable stepper motor that responds to a 5v referance signal IIRC.

    you can usually loosen the TPS sensor screws and move the sensor slightly.

    it can change the idle speed
