Please refer to the Maxima/I30?I35 FAQ sticky in this forum regarding DTC codes. For the 4th gen Maxima, P0158 (Max Voltage Monitoring) and P0159 (Response Monitoring) refer to problem with the Rear Heated O2 Sensor, Bank 2. You have to replace this sensor. If not, the catalytic converter may fail and that is very expensive to replace.
DTC Code P1320 refers to problem with the Ignition Signal Primary (Ignition Coil) - ignition circuit harness or connector; power transistor in ignition coil; condenser; or crankshaft position sensor.
Please download a copy of FSM (Factory Service Manual) and go to EC (Engine Control System) chapter. It will give you instructions on how to do your own diagnostics, interpret the DTC codes and isolate the problem.
