One problem related to o2 sensor has been reported for the 1998 Nissan Maxima. The most recently reported issues are listed below.
I have a 1998 Nissan Maxima I now have to replace all six coils, maf mass airflow, all spark plugs and wires, all three O2 sensors it stalls, runs rough, and cuts off. Now it will not start. I have read numerous complaints about this problem and noone seems to want to resolve the issues the customers are having including me. Seems like Nissan needs a recall on these parts it is very dangerous for the car to shut off in the middle of traffic.
