Well my dads friend just got some kind of thing that checks whats wrong with the car(computer.) And the "gadget" since i dont know what its called says that the problem is "Air/Fuel sensor circuit range/Performance(Bank 1 sensor 1) Probable Causes 1.-Open or short circuit condition 2.-Poor electrical connection" anyone know what the problem is and where it is located? P.S. I dont know if anything is wrong with the car, he just said to ask and see whats up. He also went to pep boys to troubleshoot and their computer said the same thing(he probably forgot to ask how to fix it.) Thank You!
