Yes the R34 coil packs are complete bollocks, my last R34 had them die, first it was a miss at idle, then the light coming on, then I started losing cylinders and sounding like a WRX. They must have had an extremely bad run with the manufacture of certain lots. They CANNOT be repaired with any of the methods stated on the forums, once they die they die, it's heat related so the car can run fine basically until the engine is up to temp and heat-soaks them.
My current R34 is just starting to miss at idle, so I'm going to get some splitfires ASAP before I get the headache of dead cylinders that crop up at the worst of times.
