Ive been troubleshooting a OBD2 not ready on my O2 and CAT moitors and have been looking my lambda(pre cat) and post cat O2's. The Post cat really looks like one has a issue. Thoughts? I know the O2 monitor uses the pre and post Cat O2s and so does the CAT OBD2 monitor. Is this a smoking gun to swap out the post cat O2s?
