Idle speed goes to 22000. Once you put it in gear drops to 1600.

Replaced air idle control value.
Fan clutch and cleaned throttle body.

Welcome to 2CarPros.

Have you checked for engine vacuum leaks? That can cause the idle to be high. Also, is the check engine light staying on when the engine is running?

Here is a link that explains how to find a vacuum leak:

Let me know. Also, let me know if the idle speed changes to normal under any conditions. For example, when it is warm or when the AC is turned on.

Let me know.
