So I've been logging stuff with vt, and I've found out that with whatever map I use (lean or rich or stock) both my Actual and Desirve AFRs are 15.1 to 15.4.
I've been messing around with stoich but I turned it back to stock a while ago.
Could it be dirty carbonized plugs? Or maybe carbonized o2 sensor?

Re: Lean mix
You should see a change in the Actual AFR beyond 15.1 - 15.4 especially once you go into open loop.

Re: Lean mix
have you checked how much does the "Closed loop air fuel additive 1" differ at those cells of interest?

Re: Lean mix
So after a good while, I fixed it. It was one of the vacuum hoses, actually, the one going to the SSV, it was cracked. I also suspected of a faulty precat gasket, and the same, it was all burnt and ripped, I changed that, changed the hoses and now it's all gucci.
