Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. One thing that comes to mind is a shorted harness. If spark is erratic when the problem occurs, check the wiring harness along the valve cover that the White wire (signal to the base of the power transistor) goes through - had one where the harness wore through into one of the valve cover bolts and was nicking the White wire, causing an intermittent, momentary loss of spark and setting the code P1320. Check this and see if in fact that is what you have going on here.
Have a look at this diagram and see if this is what your needing.https://dl.dropboxusercontent.com/u/104923897/Igntion%20Jul%2027.pdf
See the other side of the diagram in this link. Follow the wire and it will show you which pin is the PCM.https://dl.dropboxusercontent.com/u/104923897/EEC%201%20Jul%2027.pdf
With everything you have replaced I would suspect the wiring is about all that left unless the computer is at fault.
