Check all the grounds in the engine compartment. Especially the injector grounds on the RHS cylinder head. Clean and detail them even if they look good.
The injectors, and any of the sensors at the front of the motor, can cause a non-running situation, so if they're dirty, they can cause a misfire too.

At first, it was just a slight stumble under load. as long as I didn't push it, it ran fine. It has been getting worse. Now it runs rough at low RPM and idle, smoothes out between two and four grand, and starts to break-up again above that. I checked the ignition by using an ohm meter on the ignition coil and the DC resistance is in the middle of the range called out by the shop manual. I tried pulling each spark plug lead individually to see if the engine got worse or remained the same. Each pulled wire made the car run worse, so it's not a bad plug or something that could be attributed to any one cylinder. I checked the distributor and the rotor and they seem fine. Any ideas?
