5rebel9 Posted July 29, 2021 Report Share Posted July 29, 2021 (edited) Under the conditions you post, I would be looking at the EGR Valve and piping. If I understand your post you are watching "live data" from the scanner, and NOT getting a CEL or codes? Also did you make sure there were no exhaust system leaks(cracks) between the upstream and downstream sensors?

Summer Solstice Posted July 29, 2021 Report Share Posted July 29, 2021 (edited) It's times like these when it may be beneficial to have the problem diagnosed by a trusted garage. Even though the fee is usually around $100.00, you have already spent that in time, materials, and frustration. You don't have to have the repairs done there. As far as fuel rich and chugging, there are so many different things that can throw the balance off. You may have a gasket leak, a spark issue, a sensor problem, or an impeded or leaking exhaust. You've already hit the easy stuff that I would have suggested first. I say cut your losses and have a shop give it a first hand look.
