Usually you don't. It's all computer controlled. I suggest cleaning the throttle body and IAC sensor. They tend to get clogged with carbon. Check online or youtube on how to do it.

idle speed is controlled by the idle speed control bypass air valve. assuming that it is good , there is also an idle air adjustment screw . it is near the throttle position sensor . .it has a metal cap on it . turn it ccw . caution .dont adjust the throttle stop srewunder the dash pot

go with Jogger, turned mine all the way to the right and the car wouldn't start. with motor cold start it. spray a little carb cleaner on the vac lines. if the motor stammers or stalls you have a leak. have a fire extinguisher close just in case.
