If the plug wires are to close together can it cause a motor to misfire ?

If the plug wires are to close together can it cause a motor to misfire ?

NO, not if everything is in good condition. However, if provoked by high resistance in the wire (damaged carbon core) or plug (fouled), the current will take the path of least resistance, usually to ground and then that cylinder won't fire because the current never gets to the plug. Wires will occasionally arc to another wire next to it and cause that other cylinder to fire out of order. This is especially true of cyls 5 and 7 on a Pontiac, thats why the factory wire looms kept those two wires about 2 inches apart. That said, if your motor is misfiring, its almost always due to a problem completely unrelated to how CLOSE your plug wires are.
