Among the most important factors in having a smooth running car is a consistent idle speed. Having the incorrect idle speed can lead to a variety of different issues. There are a number of different components that have to work together in order for a car to idle properly. The idle control valve is among the most important components that will help to ensure that a car idles at the right speed. When trying to start the engine when it is cold outside, the idle control valve will assist the car in getting going. Each time the car is cranked, this control valve will have to work in order to ensure the smooth running of the engine.

Most car owners are surprised at the amount of carbon that their engine produces. The buildup of carbon over time can make it very hard for things like the mass airflow sensor and the idle air control valve to function. The more carbon that these components start to acquire, the harder it will be for the air to pass through them properly. The idle air control valve on a vehicle is supposed to last as long as the car does, but this is usually not the case. Due to the excessive use that this part gets and the amount of heat that it is exposed to, the idle control valve will wear out over time.

Not having full use of the idle air control valve can lead to a number of different issues. The inability to idle properly can make driving a car a very daunting and frustrating experience.

When the idle air control valve is damaged, here are some of the signs that you may start to notice:

  • The engine is stalling out on a regular basis
  • The idle is very high when the engine starts
  • The engine shuts off when the A/C is turned on
  • The Check Engine Light is on

Taking notice of these warning signs is the best way to reduce the amount of damage that is done to the vehicle. Having a [new idle air control valve installed]https://www.yourmechanic.com/services/idle-control-valve-replacement can help to restore your engine back to normal.
