code P1320 IGN signal primary

having problems with r34 non turbo engine light keeps coming on mainly when cold or when revs over 5000rpm and starts to miss sometimes is also running rich

so far have changed coil packs (spit fires) plugs , ecu, airflow meter, cas

and has not really made much difference

has anyone had similar problem

next thing to try is tps or get injectors cleaned or fuel pressure reg

and info would be a great help thanks

Is it causing an actual problem with the car?

Seen as you can read the code, can you also monitor/log data?

I would be doing that with anything ignition related that you could think of. RPM, Ignition angle and anything else that looks related. See if anything drops off all of a sudden.

Did you replace the coils with brand new ones? Try checking the wiring for problems. You can use a multimeter to check for resistance between the coilpacks and ECU etc. But multimeter wont always show a problem, as it may need some electrical load before it loses continuity. Still worth a look
