Maybe the problem is not the ignition.  Check your engine temp sensor for
the EFI.  I would even bypass the sensor with a known good warm engine
signal (some appropriate resistors instead of the sensor to give a warm
engine signal).

Sounds more like you are going way too rich.  Misfires and stumbles may be
due to the mixture and not the ignition.  The sensor may be having a
vibration problem.

Food for thought...
