Where is the Egr valve for 1990 Taurus with 3.0 with V6?

The EGR (Exhaust Gas Recirculation) valve on a 1990 Ford Taurus with a 3.0L V6 engine is typically located on the intake manifold, near the back of the engine. It may be somewhat difficult to access due to its position, often requiring you to remove other components for better visibility. Look for a cylindrical valve connected to the exhaust system and the intake manifold, usually with a few hoses and electrical connectors attached. Always refer to a repair manual for specific details and diagrams for your vehicle.
