WRT weak spark - can we assume that cap, rotor, coil wire, and plug wires are in good shape and that low-voltage wiring to the coil and other ignition components have clean connections and test out OK?

WRT warm stalling - does anything change if you unplug the EHA connector on the front of the main air intake? I am wondering if it is going to full enrich and killing the engine as it warms up.

Also - can you hook a dwell meter or a DMM with a duty cycle reading to Pin 3 of the diagnostic socket and tell us what readings you get as the engine warms up?

There is a ton of information on these components on this forum - you might try poking around or a Search.
