      i replaced the sensor on the drivers side and i am still getting the same code and problem.

      it also says it could be. injectors,low fuel, vacume leak.

      i really think it is fuel due to my bad gas a few weeks ago. i think my fuel pump is starving and not pumping out the needed amount.

        usualy. if the pump or fuel system is the problem you will get both banks setting the code. but not always. you could always check the fuel filter and do a pressure test to see. I would also be checking for an injector unpluged. a missfire can also set a lean condition. As can an exhaust leak before the 02.

          Maybe your fuel filter is clogged...

              a got a scanner from work. it says bank 1 and 2 are lean but after the cat is rich. it might be the placment of the sensor since i got a custom s pipe made.

              Fuel pump. if it gets too hot will it shut down until a certain temp is reached?
