its an 05. what do you mean by have the codes tuned out? i thought there had to be some kind of reading coming from the rear o2?
mgolin: 3800performance.com makes a rear o2 sensor delete. it plugs directly into your harness, so if you can get your sensor out i guess you could just leave it in there and zip tie the pigtail up to your car. if you do want to get it out get a torch, heat the pipe up around the sensor and then try to remove it. heating the pipe up to a cherry red and then cooling it down with water extremely fast will also help break the sensor loose especial if the sensor is already bad...
