I have a
p0171 System too Lean (Bank 1)
My cat has been gutted for a quite a few months now and I just I put a MIL eliminator on the 2nd 02 sensor. The CEL came on about a day and a half later. Could this have anything to do with my sensor? The fella at autozone told me to take it out and clean it... but I figured I'd ask here first heh....
