I don't know where it was on the F-bodies, but I assume in the manifold right at the head. I had thought of your previous posts in adjusting the int. delay due to this, but haven't done so. I hate spending more time on the MAF setup when my intent is to dump it.
The INT delay has caused these issues many times. INT changes and looks at delay it takes to reach O2 sensor before adjusting again. To short and makes another adjustment to wrong part of exhaust gas that was not adjusted, wrong again, wrong again... it keeps freaking out because nothing is right? Increase delay by 50% and try... or run Open Loop and see if the problem goes away will prove it's a CL feedback issue.
