High idle (HOT) - Page 2

I just disconnected the battery, got a new fuel filter installed, cleaned and reoiled the air filter, cleaned the mass air flow sensor and cleaned the pressure regulator. I too have a high idle, basically it never drops when I reach operating temperature. I did have it flushed and install a new trd t stat. No cel. Seems when the ac comes on it drops a few hundred rpms, like its stuck on high idle.

disconnect the battery for 15 minuets and let the ECU reset.

Did you guys ever figure this out? My Tacoma is doing the exact same thing and I'm not sure what the cause is yet. I am suspecting it may be the IAC.
