So the problem doesn’t seem as bad as it was, but today I took it out on the freeway and it seems like it’s running rough and misfiring at high speeds, right around 3,000-3,500 rpms. I still see little jumps in the tachometer every now and then driving at low speeds too. Any ideas?

or,,,, the voltage to the ICM is wrong-bad-or unstable.
test the parts, autozone has the equipment.
verify the proper voltage to the dist.

I brought it on the freeway today and it runs good all the way til when I’m cruising at about 3,000-3,500 rpms and then it starts to misfire, tachometer slightly jumps, and seems like an occasional backfire As well. At about 3,000-3,500 rpms the engine even sounds like it changes sound to a bit of a lower rumble. I put a new vacuum advance on the distributor and that didn’t change anything.
iv changed:
ignition control module
ignition coil
vacuum advance
Any advice??
