Upon seeing the ECU, the first reaction of a mechanic at a VW bus meet
I went to recently (Catherine Creek Oregon) was that someone reversed
the leads when jump starting the vehicle.

I pulled the ECU and wiring from a non op '93/94 Jetta. The vendor had
a great reputation, and the engine he sold me is indeed good, so I
assumed same of the ECU and harness.

In trouble shooting the intermittent running issue, I spent many hours
working on things I assumed I'd done wrong (wiring) or simply trouble
shooting various parts and systems. All good learning experiences, and
I did find faults in my wiring work, but the minor running issue was
almost certainly due to the ECU.

A private email inadvertently reminded me of the 3 hall wires from
distributor connector that were cracked and twisted together. I assume
they must have shorted out at some point. The entire engine portion of
the harness had cracks at quite a few wire casings.

Thanks for the input folks.
