Safe to get reflash with cel on?
Safe to get reflash with cel on?
My cel is throwing a o2 sensor code that controls air/fuel ratio? Not exactly sure about replacing it because I'm worried about it going bad instantly. Im running i/rh/e and have a eliminator/defouler on the catalytic converter o2 sensor. Would the reflash be ok or safe with the current set up? Would it make things better or worse with the o2 problem?
