My primary o2 sensors are not reading at all. I replaced the driver's side with a brand new bosch and it's still not reading. I'm basically driving in open loop everywhere I go. Anyone ever had this kind of issue? I have no CEL on and it seems to run fine other than terrible fuel mileage and idle surge.
