Where is the egr valve located on a 1992 Chevy Corsica 4 cylinder?

On a 1992 Chevy Corsica 4-cylinder, the EGR valve is typically located on the intake manifold. However, the exact location can vary slightly depending on the specific engine (e.g., 2.5L or 2.8L). It's usually near the back of the intake manifold, relatively close to the firewall. To be sure, you'll need to consult a repair manual specific to your engine's displacement. A diagram in the manual will give you the precise location.
