actually just bought my first 300zx. It's a bit of a mess and is running very rough. Just went through the plugs, found one coil pack was not plugged in and hoped that was the problem, but it's still running rough. No check engine light or any indicators. I assume a fuel injector problem but which one? need to buy a OBD1 scanner I think?
Engine was missing. Installed new fuel injector plugs and cleaned contacts of fuel injectors and now running on all cylinders again.
injector #2 failed, replaced fuel rail and injectors with new style. then injector #3 failed right away.
difficult to start when cold.
