Jeff Doyle apparently deleted. What are your LTFTs (block 032 with engine off ignition on)?

Default moral of the story, homebrew without a wideband and/or ECUx is tough.
I'd suggest you get one, the other, or both to successfully homebrew because maybe you were too rich and killed 02s or something.

good point will do.. specially wideband... u think running to lean could also kill the o2s

Default i have similar condition after oil change, turns out the oil level is a bit high
suck the excess oil out and everything reads normal and cel goes away
