A fault that was widely publicised but with no credible answers at that time. People's understanding of why some Prince engines misfire when hot may …Bad spark plug wires are a common cause of misfire codes. After 50,000 or so miles, the OEM wires may be leaking current to ground or other wires, shorting the spark before it can reach the plug.
