My 1975 350SLC (8 cyl.) was running down the highway like silk the other day. After stopping for a traffic light, I rounded the corner, the car stuttered once, then quit. No amount of cranking (new battery) with or without starting fluid would elicit any response whatever. After having it towed home (the shame!!), I have found that it has a very weak spark at the plug and a weak spark at the coil (1\16" max.). Can a coil or a condenser just go instantaneously yet still show weak signs of life? What else should I look for? Regards, Ron
