things that may or may not help... first off the dme won't shut off the spark to an individual cylinder if there's no continued circuit on the fuel injector.

It has a feature in the DME known as the catalytic converter protection on your car which is dme version 3.1.
This feature will shut off the injector to any cylinder that a fault is detected in the coil primary circuit. The later cars which have 3.3 and higher monitor the primary and secondary ignition circuit and shut down the fuel injector if needed,but yours only monitors the primary. This is to keep from dumping raw fuel into the cat.
If you have a injector fault it won't shut down the coil since spark without fuel won't cause a cat to overheat

Next since you have changed the dme and the coils both, have you checked for voltage at terminal 3 of the coil connector with the key on?

All of the coils have 12v at them when the key is on and the dme makes and breaks the ground to trigger the spark. If you look at the harness you'll see that all of the coils have a junction point in the harness where they all meet for the positive supply line. If you don't have 12v at terminal 3 with the key on then back trace it and find out at what point you do.
