I have a question about the O2 sensors. Would a bad sensor kill the gas mileage? I have an 08 CVO Ultra and the gas mileage has gone south on me. I didn't have the check engine light come on although there is a code saying rear sensor lean. I just thought I would check and see what your thoughts were on this.
Thank You
