Alright, so here’s my situation. My Corolla has been running lean (or so I’ve heard), and now I’ve got the P0171 code. Fuel mix issue, right? I recently changed the air filter, but that’s it. Do you think that’s the culprit, or am I in for something bigger like an O2 sensor failure? Really don’t wanna deal with that
