So I pulled out the patch that intercepts the fueling and o2's and disconnected and reconnected firmly and I haven't had the issues since. This actually makes senses because everytime I uninstalled my tune and re-installed it, it worked great for a few thousand miles, than all of sudden it would happen again.

I would check the patch that on the JB4 that intercepts the o2 ad fueling and maybe bend the pins a bit to get a better connection.

See if that helps and it doesn't cost anything.

ALSO I have had my cylinders cleaned out about 4k miles ago.
I believe I started to get this too. I disconnected and reconnected everything while adding a usb cable into the glove box so I could log what is going on. However, after reconnecting everything the issue has not come back. (obviously going with cobb would simplify this issue).
