Hi, new to the site to today and have a ignition problem. Just installed a HEI distributor kit, a 45,000 volt coil and the problem is a intermittent miss, backfires under acceleration, but the concern is not always present. Had bypassed the resistor wire at the ignition switch and run a new wire to the coil, should I have also included green/red wire ? This is on my 68 mustang. Thank you , Fred
