Report "I have a Plymouth Grand Voyager Mini-van. 3.3 liter V6. I've been having problems with the 3rd and 6th ports not firing from the ignition coil. Turns out that something is causing the ignition coil to burn out on the 3 and 6 coil. The last coil pack actually burnt and melted through the back. I've tried even a different used Power Train Module (ecm,) and same thing happens. Wires and connectors visually look fine. No rust or corrosion. Any ideas on what could cause this? This is starting to drive me crazy!"
