1990 Accord with erratic tach and hesitation

I have a 1990 Honda Accord EX with 217,000 miles. Started hesitating when accelerating and the tach jumps between 2500 to 4000, all over the place. I can feel no difference with the engine. Replaced the ignition mod, distributor cap. Not getting any error codes and no CEL light on. Thinking it might be the coil, or maybe the distributor housing unit?

Yes, this was a brand new ICM, matched to the manufacture.
