Here is what I have. I have checked both locations no EGR valve.looking at both pics from STL and YRAC ,I think I know why. Where it shows YRAC's I have a plate covering where it should mount. So some one took it off or it never had one.The vac diagram under the hood does not show the EGR Valve. Now I need to purchase the valve and vac lines and install them. Does any one have the diagram for that?
