There is a good chance it could be your fuel pump , however if the check engine light is coming on and the dealer cant tell you what is wrong , try a different dealer or another shop. Second opinions never hurt.

SOURCE: Kia Sportage 2003 - Solenoid Valve

This sounds like the idle air control valve. This valve sits on the inlet manifold and basicly regulated the flow of air for tickover( or idle). The usual operation of this valve is, when the engine is running at high speed the valve will be closed, when the engine comes down to idle, the main throttle butterfly will shut as you lift your foot off the pedal. The idle valve will open and give a small amound of air to the engine, just enough to run it at idle speed. These valves can stick open, therefore letting air in when the throttle is open, giving the engine too much air. WD40 is only a temporary repair untill it jams again. Best course of action is to have part replaced.

any aftermarket brake fluid will be fine. the actual grade is located on the top of the fluid cap. you can find the universal grade at your local auto parts shop.
