My check engine light came on, I went down to Auto Zone and had them do a check engine diagnostic, and it came back as EGR Valve failure. I replaced my EGR Valve and had them reset the light, and it went off, but about 15 minutes later, the check engine light came back on. I checked the connection of the valve and the wires connecting into it, and everythings connected properly. What is going on and what should I do?

The EGR passage in the upper intake manifold is probably restricted with carbon deposits. You will have to clean it out with a coat hangar wire and some good cleaner. (GM Top Engine Cleaner) or (Sea Foam)
