Good morning.

Lets start with the code. Do you have the code number?

Idle at five or six? is that a low idle or a high idle like the motor screaming?

Okay.

Code number? If you do not have it, a parts store can read it for you for free. once we know the code, it will lead us in the direction of the failure.

The high idle could be from a vacuum leak. Check all the hose for either being cracked or broken. Look for any that may be disconnected as well. This is one of the causes for high idle.

Otherwise, it could be the throttle body or the idle air control valve.

As I stated, you can go to a parts store and have them read it for free. Then let me know the results so I can further help you find the issue.

Hello PAMELA BARRIENTOS,

If you decide you would like to conduct the scan yourself here is a link to an article from this site that features written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

Once you have the codes please get back to us with the code number(s) so that we can further assist you. We are always happy to help.

Thank you for visiting 2CarPros.com.

Kindest regards,

Renee
