It sounds like you need new rear o2 sensors if you are throwing these codes. I'm not sure how adding a lid caused these to go off. The rear sensors are just there to see if the cats are working. I guess if the lid really messed up your air/fuel ratio this could happen, but I havn't heard of it before. Hopefully someone with more experience will chime in.
