The ONLY thing you haven't replaced is the ignition ECU... Do you understand how coils build up HT electricity? Normally grounded breakerless module (or points) momentarily breaks that ground, causing the coil to suddenly build up a high voltage charge, which is then passed to a plug as the distributor rotor passes it. If it for some reason fails to break the ground -- no spark. If it doesn't break ground long enough -- weak spark. If it breaks ground too long -- burned up coil. Bosch ECU of course has to adjust dwell times to yield a consistent spark over the entire RPM range. Yours may not be doing that. Try swapping it with Mike's.
