There are quite a few potential problems that can be caused by a faulty EGR valve:
Lean burn, which can result in damage to the valves and/or pistons, caused when the faulty EGR valve allows too much fresh air into the intake.
When the opposite occurs, (too little fresh air), the idle speed can drop potentially not idling at all.

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.
