1991 Nissan 300ZX - 3.0L V6 120,000 mi,
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?
