Well, my theory (and I know some don't believe that) is, that
when an ignition wire is broken, the voltage rises so high till
the spark can jump. The energy is stored in the coil and when you stop
the current in the primary coil, the current still wants to flow.
Now the primary circuit is open and the current can't flow anymore under
regular circumstances. The magnetic field in the coil induces a higher
voltage in the secondary winding (also in the primary, but the switch in the
primary circuit (points or transistors) can handle this). The voltage rises
until the field strenght lets the spark jump at the weakest point (ionized
air...therefore there's a difference in the max voltage if you have
different air/gas mixtures around the spark plug). This should be the spark
plug (therefore when you make the gap wider you get a higher voltage).

Now let's say your main wire is broken - you have a second gap where the
spark must jump over. The result is that the induced voltage in the coil is
higher than under regular circumstances. The high voltage is also induced in
the primary winding and may jump in the primary circuit somewhere. These
extra needles that the tacho will see let it jump/move like crazy.
And the car sputters because the spark jumps somewhere else but where it
should - at your spark plugs !
