Been there, done that. I've had my '86 for 27 years and have gone through the wiring and connector issues for some time now. Bob Lincoln and I traced my entire harness only to find a connection at the computer in the kick panel. I pulled the connectors and several of the spring connectors had lost part of their 'pieces'. I mean that part of the spring connector had fallen off. This made it nearly impossible for the connector to make solid connection to the pins. I replaced them and the problem finally went away.
I'm not saying that is your problem but between Bob Lincoln, you and me I'm sure we can solve these problems.
Check out the link in my signature for a page about error codes and drivability issues. Bob Lincoln and I co-authored this and hope it will help you solve your problems.
The harness in question here is the one which goes behind the valve cover. It's baked by the heat of the exhaust. In my case the insulation had flaked off the wires so they were either touching or grounding. I had to replace the harness or rewire it to solve the problem. Also the connectors at the ends of the harness throughout the engine compartment tend to tarnish and make bad connections. Consider disconnecting every one, one at a time, and clean the connectors. Tighten where possible each female connector and use some dielectric grease when reconnecting.
Please keep us informed as to your progress. One of my '86s (the one I've had for 27 years) has over 321,000 miles and on my trip from Tampa this past weekend performed very well providing 31.5 MPG.
