Expert:  david craig replied 6 months ago.

The EGR Valve on this 3.8 L engine should be in front of the throttle body on the drivers side of the engine just to the right of the front valve cover. If you locate where the intake tube/duct attaches to the throttle body and then move just a few inches toward the front of the car it should sit right in that spot. It will have two bolts attaching it to the intake/tube. Hope you find it!!
