BE sure to check the 25amp blade fuse located in the engine compartment.
It's on the drivers side fender and is the main fuse for the fuel pump-ignition. It has a red wire running directly to the positive battery terminal. pull it and see if there is any corosion .. it's cheap so replace it anyway.
this fuse due to it's location can get wet - also check the holder for corrosion as well as the post on the positive battery terminal. clean the connections. IPD even sells a special waterproof holder for this fuse as it is infamous for causing problems in LH injected Volvos. Its location is one of those Volvo engineering mistakes that were never corrected by Volvo.
this fuse and bad contact at the holder can cause many strange problems but is often overlooked. I did not see any mention that this fuse was ever checked in any of your posts.
Re: the ignition wires. I had a missing bucking problem on my 87 that I could not figure out - I went so far as to replace the Hall Sensor in the distributor. But the problem turned out to be a bad ignition wire...even though the set was new, just a few months old. I found it by doing what Don Foster reccommended- a midnight viewing. You might try this to eliminate a short it the ignition system. In the dark of night or in a dark place while the car is acting poorly. open the hood and (it needs to be very dark) look at the engine. any electrical "leaks" will be seen as blue flashes. On mine I saw blue arcing along the bad sparkplug wire. If the Hall sensor in the distributor is arcing you should see blue around the distributor.
