Diaz410 Posted February 22, 2023 Share Posted February 22, 2023 I recently bought my first car a 01 Es300 and before I bought it I took it autozone to have its problems read and on the report it says. Replace Air/Fuel Ratio Sensor (AFR) It also shows a suggested part, A oxygen sensor. Should I buy both upstream and downstream oxygen sensors? And also the Air/Fuel Ratio Upstream Front and Rear? Thanks for your time. Quote Link to comment Share on other sites More sharing options...
