Chris,
I'm either missing something, or failing to make my point...

1) PO didn't just "reconfigure" the FI relay, he "killed" it by removing the ground on terminal 31 (and thus killed the Lamba operation)
2) Mike installed the new harness "about a month ago" (no problems noted)
3) Mike's rich-running problem began as soon as he restored the FI relay operation. My "guess" is that ...

A) The newly working FI relay also restored the Lambda operation.
and
B.1) Restored Lambda operation + mis-connected WUR/FV plugs would drive FV wide open causing "black smoke"
or
B.2) Restored Lamba operation + maladjusted mixture at F. Dist (by PO, to run with no Lambda) could cause rich-running

But all (my current) bets are off — If PO somehow kept Lambda working with NO FI relay. Still too many unknowns for me.
