More O2 problems
I have a 2001 Maxima Se. The check engine light has come on and off for a couple years. The first time the mechanic replaced the ignition coils. Took about 100 miles for the light to go off. It came back on about a month later. This time it was the Air Mass meter. The light came on a few months later. I waited until inspection time, and this time I needed the entire catalytic converter assembly replaced. It's back on again. I'm getting code P0171. Which I know is bank 1 O2 sensor. It doesn't make sense that all these things keep needing replacement so soon after something is replaced. Is it normal to have such a train reaction? I totally trust my mechanic, and I only have 95K mi on the car.
