I can't figure out why the check enging light didn't go out after I replaced the 02 sensor and that was the only code that came up for the light being on, So I changed the 02 sensor and after about 5 minutes of driving the light popped back on so I did the dianostic again and the same code came up so now I'm lost.

    It was a bosch brand o2 sensor, But I'll get a a/c delco sensor and see what happens.
