My check engine light is on. OBD2 code P0430, P0420. I changed both driver's side O2 sensors. Mass air flow sensor looks good. Gas mileage seems normal. All 4 O2 sensors have off the chart ohm reading. With further OBD2 research I found: STFT Bank 1: 0.0%, LTFT Bank 1: 6.2%, STFT Bank 2: 2.3%, LTFT Bank 2 3.9%. What should I try next?
have the same problem?
