cressida 7mge is 650 too I think. at least that's what I've always seen them idle at and what I've always heard. idle is computer controlled though, you shouldn't do anything but make sure everythings working right.
when installing the TPS, align it so the idle switch contacts are closed when the throttle plate is closed but open as soon as it moves. (.058mm gap between the throttle stop screw and cable pull lever)
