Was running great until about 2 weeks ago, started having a bit more chop at idle and lamda was running very lean (1.2 -1.35) at and just up from idle, but when driven harder it really smoothed out WOT was fine .82 - .83 right where it is set to.

Thought I had it fixed last week but now I can't really even drive it as part throttle is so bad.

To me it seems like when it is running in closed loop something is very off and it is running very lean and in open loop it is good.

Going to swap out the O2 sensors to my last known good ones as the last change I did was take out the cheap ones to replace with OE ones and pull the secondary ones as they have been programmed out.

I was also thinking like many it was some kind of intake leak but I did spray every part of the intake with starter fluid and could not get even a blip of change in rpm.

I am about to tap out and bring to a shop, not something I like doing but this thing is kicking my butt.
