I've had an old set of wires cause a misfire on a cylinder before.

I had that happen more than once im my Miata.
The wires short out thru the insulation to the zylinder head rather than transmitting the power to the plug. It always seemed to be most noticable at low rpm's.
Once it happened on a road trip, and I just wrapped the defective wire with tape in order to make it home without ruining my cat.
I let the engine idle and pulled one plug wire at a time. The one that didn't make any difference was the defective one.
