BTDT, sorry you are too. When it's good, it's great. When it's bad, it's
not so great.
Per Bently (in no particular order):
Check your fuel pressure regulator for correct values
Check the Hall unit
Check the fuel injectors for correct fogging pattern (as opposed to
straight streaming)
Check/replace your Coolant Temp sensor II
Do the "pin checks" for the ignition module
Do the rest of the "pin checks" for the wiring harness itself
Clean all the grounds
Hope for sanity's sake its one of the above.
If all else fails, procure a used ECU and swap it out. You don't want to
hear this but...from your #2 it sounds like you may be running on default
settings with the ECU not functioning at all.
OR
Run a bottle of Tecron with 93 premium gas first to see if it helps at all,
you never know but don't get your hopes up.
Then again, it could be possesed.
