2012 Liberty - engine loses power on freeway, clattering noise, electronic throttle light flashes followed by engine light, I pull over and there is a small fire atop the valve cover and wiring harness - pull the fire extinguisher from the back and put out the fire - hole in the valve cover - anyone ever see anything like this? (my mechanic said it's the first time anyone has ever dropped a car at his lot after a spontaneous engine fire, and it's also the first time he ever heard of anyone who had an extinguisher and knew how to use it when it was needed)
