Answers :

There is a small electric motor call IDLE AIR CONTROL (IAC).

It add rpm when there is load like headlight,radio,power window while you at idle.

Just to bump up the power a little to keep everything operate smoothly.

When IAC is not functioning it will give you uneven idle.

Get the OBD-II code and repost. It will help you to get to the real problem.

OBD-II connector is 18" from the center of the lower dashboard. Scanner is about $50 to start.
