The idle screw on a Chevy Cobalt is typically located on the throttle body. To access it, you may need to remove the air intake duct. The screw is usually a small, slotted or Phillips head screw that adjusts the idle speed of the engine. Always consult the vehicle's service manual for specific details related to your model year.
For non fuel injected models, on the side of the carburetor there is an idle screw. Turning the screw slightly will raise the idle on your Chevy truck.
there is a screw on the carb right where the throttle cable hooks to it that you use to adjust the idle.
between 500/750 depends on where the idle screw is set

The idle is controlled by the ecm, no adjustment needed. If you are having idle problems look for a vacuum leak or possibly a faulty idle air control valve (IAC).
carb problems, adjust the idle screw and see if that helps
how to turn the idle down. See if it's carburetor or efi. There is a speed adjustment for either using the idle speed screw (carb) or air bypass adjustment screw. If either has no effect, see below-

The IDLE MIXTURE SCREW (FCR) controls fuel delivery to the idle port and the SCREW is located on the engine side of the carburetor slide. Turning the IDLE MIXTURE SCREW out will make idle and off-idle richer. Turning IDLE MIXTURE SCREW (CR, PWK, PJ, PE) controls the amount of air to the IDLE and SLOW CIRCUIT. This SCREW is located on the air cleaner side of the throttle slide and turning the SCREW out will lean the mixture and turning the SCREW in (clockwise) will richen the mixture.
