Distributor or Ignitor problem ?

[mauipetr]

94 celica GT 2.2 federal automatic, doesn't want to run, coughing, stalling, rpm gauge jumps eratically up down. Computer says one code only, #12. Regarding Haynes manual it's distributor circuit or Igniter.
When engine stops rotating(ignition still on), many times there is noise from distributor cap, like zzzzz....System keeps shooting spark between distributor cap and rotor and there will be spark on that same spark plug !!!!!!
What's wrong?
Distributor or Ignitor ???
Thank you for your time
