Lean mix

[0124alexrx8]

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?

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

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

Hey, sorry for answering this late, but yes, I did check everything mentioned, and I had no luck. I'm suspecting of a faulty upstream o2 sensor.

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.
