If 1995 2001 Maxima with 3.0L engine has MIL on & P1320 code (primary IGN signal) one or more ignition coils may have intermittent internal failure.
If also has single cylinder misfire code (P0301 P0306), replacing only coil on indicated cylinder should repair problem.
If only P1320 or P1320 & P0300, it may not be possible to determine which coil has failed. All coils may need to be replaced.
One of these is for cylinder 4 misfire, but it may be setting p0325 as well. Also loosen then retighten ground by the injectors on the intake manifold. Although you need to check to see if hte harness is broken and from reading the tips you have to use nissan coils only as the others won't stop the code. This one code p1320 is EXTEMELY hard to get rid of and you should really take this to a pro to straighten it out. This is only to save you money and frustrations this suggestion.
