Chances are the O2 sensor didn't go bad when you did the work. Were there any sensors on the parts that were still on the vehicle? If so, they will need reinstalled. If I recall correctly, there is a MAF sensor TPS sensor. That should be a part of the system. As far as the evap code, check to see if there are any leaks in the system and that the gas cap is tight.
