I have been fighting a fuel trim issue. My upstream Bank 2 sensor wants to peg at1.25 at idle while my bank 1 is at .90. I data logged my O2 sensors with the key on and got .5V on Bank 1 and 0 on bank 2. I have voltage with the car running. I have done a smoke test and no intake leak, cleaned my MAF and air filter. What is odd is no trouble codes....any ideas?
