This is reported because of the common nature of this problem and the expense of repair. This is a faulty design which routes an engine coolant hose such that when the hose connection leaks, it drips onto the #4 coil pack and shorts it out. This defect has been carried over through at least three model years (97,98& 99). The cost of my repair was approx. $400. This is not normal wear nor is it a random component failure. I suspect Ford knows about the problem. As a high volume production company, their quality department has surely flagged this defect through some form of failure trend analysis effort.
