Did you disconnect the idle stabilizer?  if so was thier a change in
rpm?  I don't remeber if disconnection increased or decreased the idle.
Also, did you disconnect or check the throttle position sensor (IE WOT /
Idle sensor)  I am talking from 87 4kq land, since I don't know what
yours is, I am just restating things I have tested on when My car got a
little funny or heard fromt hsi group..

IF it doens't apply, ignore me... :-)

On my 5 cylinder JT engine i was driving along yesterday morning and
all was
normal.  Then i headed home and when i got home in the driveway the
Idle rpm
was at 1600 instead of 850.  I flicked the gas pedal but no change.
The idle
stabilizer valve buzzes fine but i'm not sure what happened...nobody
touched anything under the hood and all of a sudden the idle is super

Any ideas or BTDT?
