Some vehicles dont have EGR Valve... I have a 90 Caravan, same engine as yours, basically the same thing as what you have and it has the EGR valve, then again, same engine in my 92 Dodge Spirit and it has no EGR Valve... the EGR is just mainly an emissions thing to help keep down on air polution. If yours did have the EGR Valve, they are really easy to spot, its on the left of the throttle body and the EGR Valve even says EGR right on top of it, so if you do have the valve you will know it very easily with or without any book or diagrams.
