    Hi, my 6n has started misfiring. Before getting a code reader I ran through a few things including new plugs and coil. These didn't help and now that I have the reader it gets these:

    00609 ignition output 1. Sporadic - open/short circuit to Earth
    01249, 01250, 01251, 01252 - Fuel injector for each cylinder. Sporadic - open/short circuit

    Tomorrow I will check my Earth connections, although I'm not sure how "sporadic" would relate to these. Any other thoughts?

    Those consumers are earth via the an ECU driver(s), so if one is really on a shunt it can upset the earths on the other drivers.
