RE: Code P0171 cause
try your fuel filter? could case a lean condition.. but there are numerous things that could be wrong.. sure you didnt change the wrong 02sensor .. your other conveter could be clogged..usually and 02 sensor will pull a bank1 sensor # code to tell you the exact one.. just a lean bank could be injectors or many other problems
