Miss fire

Fuel injector does this engine have the spider set up with poppets? If so they make a kit to replace them because the system was bad right off the assembly line. You might trying power flushing the injectors. This is a special operation designed just for these, some large shops have the kit otherwise it's a dealer operation and consists of blowing a cleaning solution through the injection system at high pressure, My experience is, it works about helf the time and doesn't last long. If you don't have poppets replace #2 injector. I hope this helps you

100 psi compression is quite low.

F O R I'm thinking the cylinder walls might be washed, Do you have wiring diagrams we could use here? How in hell did you get so many points.
