Drew,
In your case the miss should be more obvious on the cylinder that's already slightly missing to begin with. .
Another way to put this is that when (if) you find a culprit, the engine RPM will be affected LESS by removing that wire, since it's missing sporadically. What you should hear is a steadier idle, yet somewhat lower RPM. Easier to detect on a dead miss, when nothing at all changes after you disconnect the wire, but still doable on an intermittent miss. Just watch out for "pyschosomatic misses" or even worse, phantom "cures."
Have you tried loosening the distributor so you can move it by hand as the engine is running? You might not have a miss, but a very slight timing issue in which the engine time is advanced enough to "skip" a beat. If you you advance the spark slightly by moving the distributor, and the "miss" becomes more prominent, then you probably have it timed about right for economy. If you absolutely must have perfectly smooth idle, retard the timing a bit until it smoothens out. Your RPM will slow some, too, so adjusting base idle speed up a bit will be required.
