Rich & others,
I have a Nissan pickup with the z24 engine. I know it is dual ignition (8
spark plugs) don't know if it has 2 separate timing sensors, but pretty sure it
has a two level distributor cap and rotary button to provide separate high
voltage circuits. I can look into it in a day or
I have a Nissan Pintara (in Australia) which is a 4 cylinder with dual plugs,
leads and coils, but only one distributor.
As I understand it, the first plug fires just before top dead centre, as it
should, and the second plug is positioned at the exhaust valve (it may even be
in the exhaust mani
