You may have an injector problem, clogged or partially clogged.
Also check fuel pressure with mechanical gauge.

Try a product called "SeaFoam" in the tank.

I would also replace the O2 sensor, if problem persists, check that injectors are firing with noid light, if firing, then you may have to remove injectors and have them cleaned.
