Does anyone have a helpful diagram or explanation where the coil packs are located on a 2000 kia sportage?

Hi there!It sounds like you may have a problem with the idle speed control actualtor.This unit adjusts air to air fuel mixture.Sometimes it can get covered with carbon and not work correctly.Try taking it off and cleaning it good with some carb cleaner.Then reinstall it and see if the performance is any better.If it is then you should replace it.Here is some info,hope it helps!Thanks It is the intake air control valve in the diagram below.
The idle speed control actuator maintains idle speed according to various engine loads and conditions. This component also provides additional air during startup. It consists of an opening coil, a closing coil and a permanent magnet. According to the control signals from the ECM, the valve rotor rotates to control the bypass air flow into the engine.
