Weird O2 sensor voltage movement.

After installing pistons, rods, lt4 high pump, lt4 injectors and low pump, suffering with weird O2 sensor behavior.

Are there anyone who can help about it?

O2 voltage movement btw bank1 and bank2 is quite different. Due to that idle is quite unstable and LTFT is abnormal.

I checked leaks , swapped o2 sensors, injectors ...ect. but no good news.
