Where would you find the EGR valve on a 1987 Cutlass Supreme 8-cylinder 4 0 L?

On a 1987 Cutlass Supreme with a 4.0L V8 engine, the EGR (Exhaust Gas Recirculation) valve is typically located on the intake manifold, near the rear of the engine. It is usually mounted to the intake manifold and connected to the exhaust system via a tube. You may need to remove some components for better access, but it should be relatively easy to identify by following the exhaust gas recirculation tube from the exhaust manifold to the valve.
