I believe it is at the top rear of the engine (between engine and firewall, just left of center (passenger side). You have to remove (2) bolts (bolted in from the back, toward the front of the vehicle), next, remove the EGR tube nut that goes to the bottom of the valve. Typically, the valve does not go bad. You can test the EGR valve by removing the vacuum connector from the top of the valve, and add vacuum to the top of the valve. If the valve works, the engine will shudder when vacuum is applied. Typically EGR problems on these are caused by the DPFE senser that is located next (toward driver's side)to the EGR valve. It also bolts in from the back with two small bolts, and has (2) vacuum hoses connected to the bottm of the switch.
