Man,, I have read all this stuff and some of what the Mechanic told you does not make sense. If you changed the plugs and they looked ok, how the heck did they get oil soaked. I have by-passed my cold start switch (again), and I can start the car fairly well. Except that it will stumble until it reaches operating temp. Oh yes, I have replaced:

Plugs
Plug wires
OVP
Distributer cap
rotor
Engine temperature switch
Fuel pressure regulator
Fuel Filter
Tranmission modulator

There does not seem to be any vacume leaks.

This did not give me any warning when the symptoms started. It started fine, I went for a drive, shut it down and went to start again about 10 minutes later and it started this crap.

Couls it be the "Brain"?
