well, because the original Japanese ones are RHD the cable comes into the throttle body from the right side of the firewall. but the US ones the cable comes through on the left side of the firewall and makes a full 270 degree loop around back into the throttle body.
it is supposed to be clipped in two or three places to secure it as it loops. mine never had these clips on when I got it and the throttle cable is literally laying on the exhaust manifold heat shield.
mine will idle up around 1500 and will come back down to 800 if I goose the throttle real quick, but I have to do it each time I come to a stop and want it to idle right.

To have the computer reset the idle you just pull the ECU and EFI fuses for a min, or remove the battery cable. then jump the pins E1 to Te1 in the diagnosis box and let it idle for a min then turn it off.
your throttle position sensor must also be calibrated properly.

other than that I wonder if you take the throttle cable loose and straighten it out enough to squirt some graphite or Teflon lube down it.
but I don't think you can lube it properly without taking it loose from the pedal and taking the cable all the way out of the cable housing.
I haven't tried that yet, im waiting to do the repairs on my motor in the next couple of weeks.
