Really high idle

[GoldOxide_imp]

Good thought, Gold, but different time zones would make it difficult.

If the TPS connections and outputs are normal, then the issue is still likely with the IACV, such as
some contamination upon re-assembly and/or assembly problem and/or perhaps a wiring/connector issue...maybe even a faulty new IACV?

No CEL for the IACV, since there is no feedback to the ECM, takes us a few steps back from the OBDII age.

Gordo, has the ECM been unplugged and re-connected, just to wipe the contacts? If not, suggest you do so AFTER thoroughly checking the TPS.

Yes, I considered that. Nevertheless, those who can manage a negotiated date(s) and time(s) might help make it work. You never know? Some people can't sleep at night and could consider something else to stimulate them instead of Netflix binging.

If the meeting invite fails, then it fails. At least it was tried and no harm done.
