Low Voltage, Miss Fire

[Goat Blower]

Low voltage shouldn't cause any sort of ignition related misfire unless your voltage was dropping below 12V. The low voltage will cause your injectors to react more slowly, which might cause a lean condition. Check the plugs and see what they say.

I'd guess there might be an arcing issue as well. Put in the garage and shut out the lights to see if there's any arcing going on.

i just found this, maybe it'll help you a little, i dunno

The ECU is capable of compensating for low voltage-slower injector opening time also.It will compensate for injector deadtime and coil dwell down to 7-8 volts.

Check that fuel pump. I've had numerous Walbro's fail on different cars and cause a high speed miss under boost.
