Yes Mike,I know the feeling. This one had missfiring issues about 4 months due to low fuel pressure. New fuel filter and pressure regulator sorted it that time but of course the owner was convinced it was the same problem again.

I think it had probably been runing on low pressure for a while and the higher pressure after the repair probably showed up the weakness on the ecu circuitary.

It does have the orange band on the injectors as said by Fiachra but current draw is just under 9A, uniform across all 4 injectors. All well now anyway.
