Like the fat kid on the "Simpsons" says, HAH-HAH!  :)

Ive been there, done that too so I can laugh.

No, the plug can be dry and still not fire. You didn't test anything
else? What was the resistance on the #4 spark plug? and what about the #4
spark plug wire? 
There is the chance your #4 fuel injector isn't flowing properly, or not
at all. Id try the little test kit that Paul described a while ago to
test all 4 of the injectors. Its quick fast and cheap. (You gotta drink 4
bottles of water tho!) Since you changed the rotor, then my previous
mentioned items should be looked at closer.

I Don't think its a thrown rod. I think you would know if it were  sure.
(Big puddle of oil under the car. Smoke. Fire. Really scarry noises.) 
Does the car run fine after you give it some gas, or does it run on 3
cylinders all the time, no matter what the throttle setting is? It could
be a low fuel pressure problem. Still, look at the other things i
mentioned first. You could just have a bad spark plug wire.

It doesn't matter as long as the firing order is 1-3-4-2. (Clockwise.) 
Hmm, let me play sherlock  a minute and ask you this:
Did you change your distributor cap/rotor and then have the 3 cylinder
problem?? If so, you could of swapped a wire and this is the reason.
Check the firing order again. 
HTH!!
