Hey Jonathan==It varries between cars. If your car is later than about 1986 it is computer controled and you cannot change it. Sometimes if the idle speed solonoid is bad or dirty, the idle will be wrong. Goodluck, Joe
A vacuum leak will also cause idle quality issues.
The correct idle speed is 1RPM x4.2-7.888
Roughly 800 RPMS while in park and roughly 600 RPMS while in drive or reverse
850 RPM,
Idle speed is automaticaly controlled by the computer. If idle speed is not correct, the car has a vacuum leak or a sensor problem.

It is not adjustable. If the idle speed is not correct, then you have a sensor/actuator/computer issue.
You don't. The ECM (Engine Control Module) maintains the correct idle speed. If the idle is out of control you probably have a vacuum leak.
check the idle speed with the car in gear, if it has a tac on the dash it should idle in gear at about 700 rpm if its too low the car will vibrate or stall.
The computer will control the idle speed anywhere from 550 to 1200 rpm's
If at idle speed, yes.
From commands sent to it from the ECM, the ISC valve opens and closes allowing air into the system to maintain correct idle speed.
