just had a thought... originally was the engine a mechanical cooling fan? I cant remember if the idle rpm increases when the fan clutch locks up when the engine starts running above normal temp(dictated by the water temp sensor and ecu).
Your electric cooling fans should be able to control the temp though, but no need to increase the engine rpm.
again I can't remember if my thoughts are correct or not lol

Have you consider cleaning the T/B.. check the IAC, sometime they get carboned up and fail to operate correctly. May need to replace it.
It cause my older TPI / L98 in my Vette to cause high idle, I cleaned the T/B and replaced the IAC to fix it.

So I think I figured it out, well so far so good at least..... I swapped the TPS and when Iremoved the old one I noticed the female part was a little crooked and sloppy in the sensor, the new one was tight..... not much else to report....
It was alot of fun wheelin it in the dunes this past weekend in Johnson Valley OHV in So Cal..... the rocks were fun too but the motor shined in the dunes..
