they said the spark was weak. I only use the ignition module as a trigger for my CDI system. I need to check if the unused wire for adding a tach is maybe grounding out or something.

I added the CDI after i was having missing at high rpm, that cured the missing. maybe the CDI system is messed up. I got the car back and i'll figure it out.

Whatever it is it's within my capability to fix. I'd like to think it's the ignition module in the dizzy.
