Is the check engine light on? Are there any codes in the computer?

Are you looking for some possible causes?

Expert:  Amedee replied 2 months ago.

I see it looks like you may be off line.

I will post some information for you on this page so that you have it when you come on line in case I happen to log off.

This engine uses an electronic throttle body. The idle is controlled by the angle of the throttle plate based on various inputs to the computer. If the engine is surging at idle or it has a higher than normal idle, this could be a dirty or faulty throttle body. You will want to start by cleaning it first using a soft wire brush and some throttle body cleaner. If the problem continues, the throttle body may need to be replaced.

Another possible cause would be a, air/vacuum leak under the hood. I would start by opening the hood and listening for a hissing sound at idle indicating a vacuum leak. Look close by the throttle body, intake manifold and gaskets. Also, don't forget to check all vacuum hoses and lines and replace or fix as needed. That alone may just do the trick if you find something leaking engine vacuum.

Another thing I would recommend to check is the APP sensor/TPS sensor as they as well as the EGR valve as they could be starting to malfunction causing this condition.

The only code that was there was a misfire code.
Expert:  Amedee replied 2 months ago.

Thank you for that information. Some of the more common causes of an engine misfiring on this condition are dirty or leaking valves, faulty ignition components and possibly an air.vacuum leak (if the vacuum leak is large enough).

I would start by going after the misfire code or codes first, diagnosing and fixing that and then going after the idle condition as needed.
