Intermittent Miss at Idle. 700 1987

I have done everything looking for a vacuum leak. I have listened, I have sprayed hoses and injectors with carb cleaner and have even used the unlit propane torch. Nothing helps the miss go away so I'm leaning away from the leak theory. I'm pretty sure it isn't spark related because the miss only happens at idle and then only intermittently. I guess my question is, would a dirty clogged injector cause this? Or could it be the O2 sensor. (It's about the only component I haven't replaced.) Otherwise it runs like a top.
