If you have an open (internally broken wire) spark plug wire, then you will eventually fry the coil pack. If you let that condition go on too long, the wires can start to leak voltage to nearby engine parts, causing arcing, severe performance problems, and even ignition component failures. The arcing still continues, but the car still runs fine. Replaced coil (ignition module) with attached spark plug wire and boot and spark plugs, checked connections. Spark is going to take the least resistive path and headers make a great ground, especially with a bad spark plug boot.
