My MSD 8920 finally went. This is the third,I sent this one to MSD and they went through it, 5 years ago. Today uponn start, not tach operation, fuse good, 8920 buzzing, car run rough, I cut power wire to 8920. Engine started running good again. Bought new 8920 off eBay. Funny how it made the engine kinda sputter ..it felt like stumble that would go away when I get on it. At least it did not melt!
