If you unplug the O2 sensor, does the engine run better?
Have you tested the O2 sensor wires?
Have you replaced the fuel filter, measured the fuel pressure, and tested the FPR?

Does to the engine runs better with the O2 sensor unplugged?
How did you test the O2 sensor wires? Which ones?
Don't guess. Check the FPR. What were the fuel pressures with and without the FPR vacuum hose connected?
Also check the fuel injectors.

no, the engine does not run better. it turned out to be the filter, junk in the gas tank, and the sock filter over the pickup. lack of fuel supply.
the injectors werre new (3 of them, 1 tested good).
