So i replaced my 02 sensor and its still running rich :3d_frown:
ill just make cliff notes.
1. Car spews black smoke when i floor it.
2. Car studders at higher rpms
3. Car seems liek it looses power at gears when im trying to gu up hills and such.
4. If i add gas to get it to 3k rpms, the rpms go down then the car sometimes stalls. If not, then it goes down to 400 rpms and works it way back up to 750.
5. sometiems at lights it idles ine for liek 2 seocnds, then it starts studdering like its about to die, goes to 500 rpms bogging, then climbs it s way back up.

It's not surprising replacing it didn't help as a lambda loop carries the least authority in an EFI system and has a very narrow control range to boot.

What made you think the sensor was bad to begin with? Did you test it? Did you get any of the codes associated with the sensor or AFR? It's never a good idea to just throw parts at a problem, especially in a case where the part is easy to test.

Nice choice. The Santana 2 or the actual Santana model?
I play a custom 22 through a mesa 1st gen dual rectofier with a single 4-12 recto-cab.
I love it.
