Throwing parts at is is not the way to go.
What is the exact code number being set now?

That's just a generic code that doesn't tell you anything specific. Your basically going to have to test the whole system to find out what the problem is. Try applying vacuum to the EGR valve first at idle to see if the engine tries to stall indicating the system is working and not plugged.

PS, that was also me that answered you on the other "pay site"
