Nice combo and good troubleshooting to this point. The board is very helpful but it's nice to see some homework done once in a while, too.
Your high idle and stumble may be a vacuum leak or possibly a fault AAR valve. Search some more on how to troubleshoot it... it involves checking for 12V at the connector but then AAR removal, a freezer, and an oven.
ALso make sure every vacuum line is good, the woven-covered originals are 25+ years old now, and injector blocks get loose now and then too.
Lastly, the cap and rotor, and green wire on distributor (that might be brownish from heat now) can cause odd misfires too.
