Just curious, why would you have mess with a TB IV??? They are about as simple and reliable as it gets.

The Thunderbolts are very easy to diagnose. If you insist on changing it, a ready to run MSD is pretty simple and straight forward. Only has 3 wires to hook up. Hope this helps, Eddie.

It probably has a bad pick up sensor (#6 or 7)
