I have a 95 z28 my car had some small misfire problems after i replaced the opti spark and now a year later my coil went out, i replaced it and it went out again after three starts, cranks fine and starts fine after a new coil is installed. Any suggestions as to what the problem is would be appreciated.

i'm not a big electrical guy but it sounds to me the coil might be staying energized and burning up. Maybe faulty ign module or possibly a short to ground on a feed wire. need to look at a wire diag.

Totally just throwing this out there, but you might tests the three grounds to the coil on the right side coil stud.
