    It's really simple..........on the bottom driver's side of the carb there is a small set screw that applies more or less pressure on the idle arm- in for higher idle, out for lower idle. I don't have a tach, so I just go by ear for to adjust for the proper idle.

    If your having idle problems and the idle screw doesn't do anything you are probably going to have to adjust your
    TPS(throtle position sensor) or possibly you MC(mixture control) sonenoid. To do these you need a volt meter and a dwell meter. I've been through this many times on my
    84 TransAm. Are you getting any codes?
