Where is the idle air control on a 1995 Kia Sephia?

The Idle Air Control (IAC) valve on a 1995 Kia Sephia is located on the throttle body. It's a small, usually cylindrical, electrically controlled valve usually mounted on the side or top of the throttle body. It's often fairly easy to spot as it will have a single electrical connector attached.

However, without a picture of your specific engine bay, that's the best general location I can give. A repair manual or a detailed diagram of your specific engine is highly recommended for precise location. A quick online search for "1995 Kia Sephia engine diagram" should provide some helpful visuals.
