Oldsmobile/Buick Repair: egr valve replacement, buick riviera, egr valves

Question
How do I change an egr valve on a 1996 buick riviera w/ supercharger?

Answer
I have never changed one on an engine that has a supercharger but usually there are just 2 bolts to remove it from the engine.

WHY do you suspect the EGR valve is faulty. In over 25 years I have only seen a handful of faulty EGR valves.
