Where is the egr on 91 98 olds?

On a 1991-1998 Oldsmobile, the EGR (Exhaust Gas Recirculation) valve is typically located on the intake manifold, near the throttle body. It may be mounted on the side or at the rear of the engine, depending on the specific model and engine configuration. For precise location, consulting the vehicle's service manual or a repair guide is recommended.
