I've been having intermittent spark issues with my MSD TL. I think it may be due to plug wires. I can remember reading some posts in the past with peeps dogging the msd wires. These are used plug wires I borrowed with the owner saying they gave him trouble in past too. I pulled the wire plugs off the ends and cut them both back on both ends. The msd supweconducter wires are a spiral wound wire with tons of insulation. The spiral wire was back even where I cut it back too. Should it be black? I scuffed it up shiny copper and recrimped the plug recepts. I'll see if they are my culprit. What is an acceptable ohms reading for plug wires. I got 99 and 105.
