I'm not getting any trouble codes or no check engine light. However, when my car is in park or neutral it idles high. What could be the problem?

Hi,

There are a few things that can cause a high idle. How high does it reach?

As far as possible causes, an engine vacuum leak, a faulty idle air control valve, or even a dirty throttle body can cause it.

Do me a favor. Take a look through this link and let me know if it helps:

Let me know.
