So if unplugging the TPS makes the ECU default to WOT and it runs smoother with more fuel then it's starving for fuel or getting to much air, correct?

Air in coolant system
Not sure if you tried getting any air bubbles out of the coolant system, have had idle issues from that as well.
Change Fuel filter, get injectors cleaned and flow tested, been reading the fuel pulsation dampeners can fail/leak which the vacuum line on the fuel rail sucks in fuel causing rich issue then the ECU compensate by leaning out and just back and forth
That's what I'm looking into on my fc3s now.

I plan on changing the fuel filter ( hope it goes well as I've read the location is a pain )
And I will be removing the primary injectors and having them cleaned, I will ask to see the flow test ( buddy of mine has the machine ) at this point I don't think I need to clean the secondaries as my problem is idle.
Fuel pulsation dampener- I've read a few things on this but not much, I need to really check it out.
How would I check the dampner?

Just spoke with the old owner and he says it was running great last time he started it, until it idled up and down while warm, then died and wouldn't start, then I looked at it 2 months later and got it started with starting fluid and it smoked like crazy. Which I believe now was fuel.
