Having problems with your 2000 Mercury Cougar ?

My car's check engine light keeps coming on, I had it checked and it throws the code for the egr valve. I just had the EGR valve replaced and the light is back on. the car also makes a loud fog horn like sound that I believe is related to the problem. What can I do to fix this?
