Diagnosing Opti symptoms are:
-codes 16, 36, 41 and 42
-car starts missing once the car warms up
-Using MSD coil (new), Standard ICM (new), thepartsladi Opti (new, but one of the last ones before she went AWOL), GM opti harness (new), MSD wires (new), autolite spark plugs (new)

Terminal A and D on the ICM driver connector both read 10-11 with ignition on.

Terminal B on the ICM driver connector read 2.1 - 2.6 while cranking.

I took a test light to terminal C on the opti harness with the ignition on, but not running and I got no light. I did however get one on terminal D.

Measuring the opti harness
-A = 5
-B = 5
-C = 11
-D = 0

Coil continuity test (MSD coil) - 4.87 ohms on each terminal

Thoughts?

Since the car is now reliably running, legal, etc. I started in on some appearance upgrades. Can't go wrong with the classic TT-Ms:

My subs have dry rotted and started sounding kinda rough:



Contacted Rockford Fosgate and got the ideal subs for my 10+ years old amp.

These were a little bigger than my old ones, so I had to squish them together. No room for the fancy trim covers either, so that makes me sad.

Sounds really good, much better than before!
