At its basic level, the spark plug wire exists solely to transmit electricity from the coil or distributor to the spark plug. Your spark plug wires are breaking down and leaking to ground. Unless the spark plug gap has become really wide, my guess is the same as db’s above, there’s a bad connection between the coil and the top of the spark plug. For example, thick insulation to prevent high voltage from jumping off the wire before it reaches the spark plug, and a rubber boot at each end to protect metal connectors from moisture, corrosion, oil, and other … There is also a time factor involved in that the field collapses many times faster (1.2 - 4 microseconds) than it builds up because of the extra resistance caused by the spark plug. To do this successfully, they need to be covered in thick insulation to prevent high voltages jumping off the wire before it reaches the spark plug and a rubber boot at each end.

They may look like your average wires, but spark plug wires have a very important job to do. If you're not getting spark to one or more cylinders, this could point to a problem with a spark plug wire. The higher voltage looks for any path to get to ground so the poorly insulated area of the spark plug wire that was doing a good job with the lower voltage now can't resist it. You are going to do plugs too aren’t you? The electrical impulse transmitted through the plug jumps the gap at the plug's firing end to ignite a compressed air/fuel mixture. With this higher pressure, the spark finds jumping the SP gap much more difficult so the voltage created by the ignition coil increases dramatically. Abrasion damage – When spark plug wires rub against engine parts, particularly sharp edges, it causes cuts and breaks in the insulation. The arcing still continues, but the car still runs fine. Arrives before Christmas. So, connect a spark plug wire between the #1 cylinder and the distributor’s #1 terminal.
