A little over a month ago my friend was driving on the highway and then all of a sudden the motor shut off. We tried everything we could and everyone here was extremely helpful. We ended up replacing the PCM, Optispark twice, the coil and the sensor the coil plugs into, and none of that helped. It turned out he broke all the teeth off his Lunati timing gear, broke the Lunati timing chain, bent 3 pushrods and 3 valves. I just thought I would let the people know that helped us out what the problem really was. I think this tought my friend a lesson, to stay off the rev limiter but it sure was an expensive lesson. LOL
