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...
