NO. Wrong. Tell us exactly how the second O2 can influence the computer.
well, its not wrong, sorry. So yes it did fix hesitation at highway speed. So how do you explain that the code was saying "bank 1 #2 o2 error, lean gas"??????? If the gas was too lean, not rich enough, jerking at highway speed, code comming from that sensor, what makes you think that this sensor is useless inn engine performance? Give us an explanation for this because i changed the second sensor and it runs perfect since then. I would like to hear what makes you think the #2 o2 sensor dont influence engine performance.
