Idling problems with '94 camaro???!!! Much help needed!
There is nothing to adjust on the IAC itself, it's controlled by the PCM. If it's bad you can replace it, but otherwise if you're having a problem with the idle and the IAC is at fault you probably need a tune to fix that.

Anyway, I don't think it's the opti if the problem only shows up at idle, usually if the opti is bad it will run worse at higher rpms.
