Try changing the rear lower O2 sensor
Hey guys, there's been a lot of talk in this post about upper and lower (upstream downstream etc) O2 sensors. Is that for the 4 cyl? I have a v6 and I seem to only have one per exhaust manifold. Is this right? I ask b/c I just got my cats replaced and noticed that there is a "downstream" plug where I thought a sensor would be. How many should there be?
Thanks
