I’m trying to figure out if my 2 pre-cats are faulty and causing all my codes to appear on my computer. Does anyone know if unplugging the two upstream 02 sensor will help find this out?
im thinking that once unplugged if my Jeep runs better that will indicate that my cats are in fact bad? If it runs the same then it actually means my 02 sensors are bad?
