I recently installed the Petronix ignitor and Flame Thrower 3ohm coil. I have wired it to the ballat resistor, one side of ballist resistor, and directly to the coil and still get a miss at 3500 to 4000 rpm.I have new *mm accell wires new denso platnium plugs cap and button. Timing is good. My ? is has anyone got the 3ohm coil to work properly? I have the factory coil back and wired to factory specs and it runs fine. I have searched for this and have come up with no solution.

Put your car specs in your signature- model/year. Otherwise, that's the first response you'll get- well, now it would be the second.

And I just searched " Pertronix" and got three pages of threads. Pertronix, not Petronix

3.0Ω coil should not have the ballast resistor connected, and if you have a condenser connected to the coil, remove it. I had that problem due to having a condenser connected to the coil.

The car is a 73 240Z 2.4L 4 screw belltops w/European needles from ZTherapy and a full exhuast. Took the condenser off when I did the installation. Thanks

Here is the best write-up I've been able to find. Great diagrams. I installed the Pertronix without any issues on my '72

I had the same issue.. the way I had it wired was cooking my coils. Should be fine with that diagram.

I wired it up by passing the coil completely,and it still sputtered and popped at 4k and the tach quit all together. I think the coil is good becuase you can feel a difference in power with the flame thrower over the stock coil. Would some one please post pics of their coil to see if I'm missing something.Thanks

Bambikiller had a good write up on this with pictures. I'll see if I saved it somewhere. I did an engine swap, so i'm doing this from memory.
