It ended up being the fuel injection wiring harness!

The factory folded the harness back on itself and stuffed it into a clamp, over the years the insulation broke down.

At idle, reach deep into the engine bay and pull/push the harness around, if the engine stumbles - you found it!

BTW the most conclusive vacuum leak test was a smoke test. I tried them all.

Good luck

Got it Thanks!
