yes, 1 part at time. this is so common this old.
so the 12 code was flashing during the instant stall or fast gross misfire.
one trick is use a voltmeter (any) at the cig lighter, to see if 12vd (13.3 to 15vdc) is steady at the drop of engine power.
the ECU does flash out 41, or 42 if for 1 pulse in 10 drop out. this tells me, you loosing High voltage , its a HV side spark failure. of some kind.
and the primary side of coil (ignitor ) is ok,
problem is from coil secondary side to spark plugs.
make sure the rotor on dizzy is not off by 1. 1 of 3 ways it fits with junky rotors. use a bosch rotor, it fits one way ,just like the original mitsubishi rotor fit.

if one way you get no spark or if one other way, spark is weak and crossfiring, i sure this is ok but needs to be stated.
the 3 ways of the rotor
1: good and aligned to #1 post. (spec rotor)
2: weak spark and too far to jump spark. (china rotors)
3: way to far to jump and can jump 2 ways. bad bad news.
