"I also have a 95 LS and am slowly replacing coils as they fail (the original ones) and am in the middle of a conversion to a much cheaper set of coils"
I've been lucky so far, as I've had no failures (or whatever) to date with 110k miles on the LS. My feeling is that the housing of the original coils cracks after a while, perhaps due to heat, dirt and pollution gets into the cracks, and this provides a path for the unit to short out to the nearest part of the head.
I will sure keep an eye on this, as some day I might have to change at least one. Hope this works.
