This switch compensates for the rpm that are lost when you turn on the ac in your vehicle. The ac puts an extra load on the engine that this switch then compensates for and puts your rpm back to where they belong.
40 - 80 psi at idle, depending on what the engine is.
the idle speed air control controls the amount of air going in to the engine so it idles at a certain rpm so it wont stall when you stop at stop signs or so it wont over rev
on the tachometer
A good rule of thumb is to look for 10 pounds of oil pressure (or more) per 1000 RPM of engine speed. Below that, the engine may not get proper lubrication.
It is normal for a GMC Sierra to idle fast when it is first started. It will idle at around 1500 rpm until the engine warms up. To get it to slow the rpm's sooner, a person can tap the throttle once and it should slow down.
It maintains engine idle rpm when the throttle is closed.
Normal is 20-30 psi at idle. 40-60 at 3000 rpm. Minimum at idle is 10psiNormal is 20-30 psi at idle. 40-60 at 3000 rpm. Minimum at idle is 10psi

About 600 RPM
Idle speed is normal.
It is controled by the computer snd should be about 600 rpm. The idle speed solonoid controls it with a signal from the computer. GoodluckJoe It should be 750 RPM after the engine is warmed to normal operating temp.
anywhere from 800 to 1000 RPM.
The IAC valve is just that...The Idle Air Control Valve. It is responsible for keeping the idle at set parameters. And yes, it can make the engine idle at high RPM.
700 to 750 rpm is normal. if the engine stalls, you may have to replace the IAC (Idle Air Control) Motor. they get stuck.
