I would service the throttle bore and replace the IAC motor, here is a guide and instructions in the images below.

https://www.2carpros.com/articles/throttle-actuator-service

CAUTION: Some models are equipped with a factory adjusted throttle plate position set screw. Never attempt to adjust idle speed using this screw, unless directed to do so in a service procedure.

Idle speed is electronically controlled by the Powertrain Control Module (PCM) through the Idle Air Control (IAC) motor, and is not adjustable.

If idle is outside of specified RPM, or is rough, or unstable, inspect and clean throttle body if deposits are visible. Perform Minimum Idle Air Flow Test if applicable.


Check out the images (below). Please let us know what happens.
