I have a 2001-02 EF Sonata with engine 2.0. I can't find its EGR. Please help.

What is your question?

I can't find the location of the EGR valve in my Sonata and I do not know what it looks like. I want to replace it to see if the idling problem goes away. I took the car to auto repair shops, but no one knows where it is. My car was shipped directly from South Korea long time ago and its engine is 2.0. Could you please help me?
