just needed to know where the EGR valve is located

I can certainly relate to times being tough. Kia as a manufacture have put a lot of technical information on line for free http://www.kiatechinfo.com/index.asp you have to sign up but its all free. The EGR valve is on the drivers rear of the engine (air filter housing side of engine). There is also a electrical control solenoid that could be the problem, plugged passage ways, a vacuum hose that could be knocked off.

stand on the drivers side of the car and look on the back of the motor towards the top its almost right under the cover
