Any idea if the HyFire ignition box is very heat sensitive? It's failing on me intermittently now, after I opened valve that lets water go to the heater core (I had been keeping it closed, and lately I've left it open). The hose that takes water to and from the heater core runs right over the hyfire, and the ignition dies (most of the time) about 10 minutes into a drive. When I install the ignition bypass plug, the car runs again.

On the other hand, the hyfire is mounted right by the side vent in the engine bay, and I would have guessed that if heat were a problem, the heat from the headers would have caused a problem long ago (I've had the system in the car for a couple of years, and unfortunately, only about 2000 miles).

All comments, suggestions, and experience with the Mallory unit appreciated.

Thanks,
