Does anyone know the symptoms of a bad HEI ignition module? My truck is skipping and popping when I step on the gas. When I double checked the timing my light was missing a beat every 3 or 4 flashes. I ran a wire from the battery to make sure it wasn't my soddering job in the ignition switch and It ran the same. I have only had the hei for a couple of mounths and have hardly ran it.
