There is one EGR valve. NAPA stocks these. Be very sure the gasket surface is clean - a leak here is nasty! It is mounted on the passenger side of the intake manifold, and is held in place with two bolts. It has a vacuum hose going to it.

Do I need to replace both of them or just one? The FSM is absolutely no help! Thanks again. Leo H. Drowned 83
