BUICK CENTURY ENGINE PROBLEM

2001 Buick Century • 170,000 miles

My check engine light is on. I took it to autozone the code it brings up for the reason of the light is the egr valve. I have changed the valve and had the code reset. It worked for maybe a day but it is back on any suggestions

I really need the exact code numbers not code descriptions you have there is more then one egr code for too much flow not enough flow etc.
