Where is the EGR valve on an '89 Voyager 3.0 V6?

EGR valve is on the back of the engine by the firewall. take off the air cleaner completely and then look down the back of the engine and you will see a round object with an elogated egg shaped base with 2 nuts holding it on. I replaced mine and my gas mileage went up to 26-27 miles to the gallon
