Idle speed is not adjustable. It is controlled by the engine copmuter. If your idle speed is too high or low you have a problem with a sensor or the idle air controll actuator. Also, a weak battery can cause the idle too be erratic
Check your IAC it may need to be replaced/cleaned
The most common cause for an engine to die out, while idling, is the idle speed is set to low. You can adjust the idle speed with the fuel injector vital screw.
The idle speed is computer controlled. If the idle is too low, there is a problem with a ssensor or the idle speed motor.
Yes, it can cause low/unstable idle or die off at idle.
mostly the tps or throttle positioning sensor. it would be a good idea to change that
On my Mercedes sprinter the cause of the fan belt vibration at low idle speed was the pully on the alternator.This pully should ratchet in one direction.
No, that has nothing to do with idle speed.
The idle speed is computer controlled. There is no adjustment. If the speed is too high or low, there is a sensor/actuator/wiring issue.
Use the idle speed adjustment screw to set the idle speed as low as possible without stalling. http://store.chainsawr.com/

An engine usually has a higher idle speed when the ac is running. If the high speed idle does not operate then the ac will cause the engine to stall.
