"...all the Bad Harness issues was pre '88, true?"

That is my belief, yes. 89 definitely not in the mix.

Tony, I'm curious how you verified the TPS contacts were closing consistently...

If they were open, which you can simulate just by pulling the connector off, the typical behavior is cycling idle rate, like someone has a nervous foot on the pedal, but maybe its behavior isn't so typical if the throttle opening is set too tight.

Aside from that, my first thought would be ignition, and Phil has you on the right path. Careful working those plugs out.
