Depends on the vehicle. They usually do not go bad. I know that some vehicles are pron to EGR problems, not the valve. The EGR port gets clogged, causing a vehicle to run poor. The port can be cleaned, I just had mind done on my 2000 Accord V6. The vehicle has not sputtered or had a bad start since.

You also need to clean the "passages". EGR valve puts exhaust gas back into the engine intake under less than full power situations. When that happens exhaust deposits build up on the walls of the passages. Replacing the EGR valve was only half the repair, you also need to clean it out. There is a tube from under the EGR valve to the exhaust manifold. That is probably blocked.
