We are close to 95K miles now and got identical problem with Air Fuel Sensor. Dealer wants to replace for $480 + tax. I guess I will go for it. But my question to 'Brandondiem" and others is how long does it take until the next time the sensor goes faulty. I just think that if I have to replace sensor twice a year or more often I might better get rid of this car. Did anyone have to replace sensor more than once?
P.S. Also great thanks to RX in Nc for this detailed topic. I basically got more answers here than I got from my dealer.
Cheers
