Welcome to Just Answer. My name is Drew and I will be glad to assist you.

 

If you have a idle concern, you will need to start with the IAC. This is a idle air control valve that the computer uses to control idle speed and prevent stalling.

If you can hold the throttle plate open slightly to prevent stalling, then replace the IAC valve first. You can try and remove it to clean but may not help. I also suggest cleaning the throttle body and throttle plate with carb cleaner to remove any carbon build up. The IAC attaches to the bottom of the throttle body.

Please let me know if you have any additional questions.

Thanks
Drew
