What are these numbers p1320 and p0325.

Hello, This code indicates that the ignition system is not getting proper voltage to one of the ignition coils. The second code is a result of the first, most likely, and will resolve with power being restored to the coil. To have this diagnosed should not take a very long time, and parts will not typically be expensive, if needed at all. In fact, many times this can be a bad wire to the power condensor or a coil. In the estimate tool linked here, just search for general or electrical diagnostics. https://repairpal.com/estimator/nissan/maxima
