mostly the tps or throttle positioning sensor. it would be a good idea to change that
Check your IAC it may need to be replaced/cleaned
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
A car can idle too low because there is a leak in the vacuum. Cracks or breaks on the vacuum hoses in the cars engine could be the cause of this.
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.
There are several things that could cause this. The first thing to investigate, though, is the idle speed your engine is set at. As with any engine, if the idle is set too low, the engine will not continue running.
The idle speed is computer controlled. If the idle is too low, there is a problem with a ssensor or the idle speed motor.
There are a few things that can cause a low idle in a 2002 Chrysler Sebring. The fuel pump may not be working right, the fuel injectors could be old, or the car could be low on oil.
Yes, it can cause low/unstable idle or die off at idle.
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.
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.
Unlikely, Fuel and/or spark are likely culprits.
Use the idle speed adjustment screw to set the idle speed as low as possible without stalling. http://store.chainsawr.com/
