Your significant clue here is:
"""""I popped the air cleaner....gave the wires on the injectors a wiggle....then she fired right up and ran fine."""""

That won't make a pump run, it won't fix an ECM, it won't unclog an IAC, it won't even make your taillights brighter or fix coffee.
All it will do is temporarily make connection to whatever connection was lost. OR - it wiggled the wire so it no longer touched the wrong thing.

Find that.
Splices?
The TBI connector itself?
Connections?
Extended wires?
Worn or melted insulation?
