random 1 cyl misfire

[SpatialTerror]

well i dont for sure know if its on one cylinder cuz i cant pull injectors 1 at a time. but im pretty sure thats what it is. its got a new cap and rotor. (i figured that was the problem) but it didnt fix it. ckp wire is fine. and the spark plug wires arent brand new but i bought em last summer and i dont have the $160 or whatever they cost to buy new ones. and i pulled the plugs there all lookin good. so any suggestions?
oh yea this is a 93 gs with a kl in it.

Problem listed by probability:

75% - Distributor (coil or ignitor, a simple resistance test doesn't always tell you what you want to know, because 20kvolts travels differently than the 1v your multimeter puts out)
10% - ECM can't figure out the proper a/f ratio because of a vac leak or the O2's are messed
10% - plugs or plug wires are no good, once again, a simple multimeter may not tell you the truth.
-5% - injector problem.

well just figured it out. water sat in my distributor and it was arcing causing a misfire. but in the process of repairing my harness for the maf i fried my probe ecu. so it looks like im back to the k8 for now. if i can find the maf for it.
