Hello,
A dirty idle air control valve (IAC), can prevent the engine from idling properly.
Over time dirt and debris can enter the IAC and get stuck inside the valve. Which will restrict airflow. This can lead to poor idle or an engine that does not want to stay running.
Many times, cleaning out the IAC can improve the idle quality.
Here is a helpful guide:

Keep in mind that if the valve is defective then simply cleaning it will not solve the issue.
Please let me know if you have any questions.
Thank you.
