Codes p1133 So I have one code for bank 1 going to a lean condition. Could this be due to the tune that is on the car. I already replaced the o2 sensor on that side the bank 1 sensor 1 but now i am getting this code again. No headers all stock till the cat back and slp lid and i have the ws6 hood and 4.10 gears. I was thinking of pulling the tune off cuz Im only getting around 270-300 to a tank so I dont know whats normal for these 2000 TA's.
My GTO was getting like 440-460 and thats with the ls2 but apples and oranges.

P1133 is set if the PCM determines the HO2 sensor is not switching enough times within 100 sec of a monitor. If you changed out the o2 sensor and the light came back on, check the terminals on the PCM side of the connector for corrosion or loose cavities. Also check the wiring for shorts.
