After replacing the EGR valve, use the diagnostic tool and erase codes then read the codes again. I had the same problem on my 97 geo metro. After replacing the egr valve, the check engine light stayed on. After a while it was suppose to clear itself but it didn't. So I went to autozone borrowed their diagnostic tool, erased the codes and then my car passed and the check engine light went off.
