Hello! My husband and I have had the same problem with our 1993 Jeep Grand Cherokee V-6. First off, the replacement coil always has to be a Mopar coil. Secondly, to resolve the problem altogether change to the new Mopar coil and harness system that was mentioned earlier. There was actually an internal recall back in 1993 that Jeep sent to its dealers to replace 25% of the coils on the lot with the new system. After years of always keeping a spare Mopar coil, we recently came by a copy of this from a new Jeep service employee who didn't realize that we were not supposed to see the notice. The Jeep dealership still refuses to take responsibility for it. Hope this helps.

I had this same problem on my `1993 Jeep Grand Cherokee.  Whenever I went above 65 mph for a few minutes then my coil would burn out.  I added a separate ground which did not help and I too carried around a spare.  What did fix the problem was when I went to Chrysler and bought the coil from the dealer it solved the problem.  I think the aftermarket coils were not strong enough.
