I don't know if you repaired your problem, but I had a problem with a Saturn that would blow the ignition coils no matter whose i put in, I even bought a set of Excell coils and blew them. What fixed it was I removed the coils and the controller they mount on and sanded all the points that it mounts to anything. I went crazy with sandpaper BUT after I put it back together I never had a problem. I put 60,000 miles on it and sold it with no more coil problems.
Just my 2 cent experience.
