THE CHECK ENGINE LIGHT CAME ON AND BEFORE I COULD PULL OVER THERE WAS SMOKE COMING FROM UNDER THE HOOD. WHEN I OPENED THE HOOD THE AIR CLEANER ASSEMBLY WAS MELTED THROUGH AND SOME FLAME WAS STILL GLOWING IN THE DRIVER SIDE AIR FILTER. THE UPPER ENGINE WIRING HARNESS WAS CHARRED ALONG THE DRIVER SIDE AND THE CONNECTOR TO THE CAM ACTUATOR HAD DISINTEGRATED. AFTER GETTING THE CAR TOWED HOME I FOLLOWED THE HARNESS BACK TO THE AMP CONNECTOR AND ALL OF THE INSULATION ON THE WIRES HAD COMPLETELY DEGRADED TO A POWDER. I ALSO CHECKED THE WIRES ON THE MAF SENSOR AND THE THROTTLE BODY AND FOUND THE SAME CONDITION. THIS IS A MANUFACTURING ISSUE: SUBSTANDARD WIRING INSULATION ON ALL WIRING IN THE ENGINE COMPARTMENT. *TR
