“I have recently contacted Ford about this problem and I was told that there was no problem. My friend has a 1988 Mustang, who has had the same problem numerous times. I am an electrical engineer and know that this problem is the result of a bad design (I.e. The ignition control module gets too hot, which causes the transistors to function improperly). This is a real problem and I hope it doesn't take many lives to figure this out. Thank you, josh shaw”
