So you have 2 WB O2 sensors and the one on the right side is all over the place and not reading steady? You replaced the sensor and it does the same thing? Just trying to understand, your post isn't really clear.

If this is true, it sounds like an injector is causing your problem. Go into more detail about the O2s reading all over the place.
