Re-program the computer?

If you want to go up, you may be able to put a physical block in the
throttle linkage, if you want to go down, I doubt you can do much.

But the point is, why?

'Anybody know how I can change the idle speed in my Santa Fe ?
Thanks.'

REPLY: I went thru this with my Hyundai local Service Dept soon after i
got my 2002 SantaFe as i didnt like the unecessary high revs when the
car was first started (especially in sub zero temps). They said that
its just the way it comes from the factory. After a bit of questioning
and personal exploration, I learned the workings of the device that
controls Idle Speed on this SUV. Its a black colored device located
right next to the throttle valve assembly and its held on by 2 bolts
with a plug in wire harness. It is simple to remove . Inside, there are
two small holes about the size of a dime. I got some sheetmetal and cut
a perfect template to fit the entire flanged area of the Device . I then
made two smaller holes in the sheetmetal directly over the present holes
in the Device , used sealant on the perimeter of the sheetmetal template
(both sides), then applied it before putting the Device back on.
Started up the car, and the idle was too low and nearly stalled the car.
So, i removed it again , made the holes slightly larger in the
sheetmetal , and reassembled. Fired up the car and the idle speed was to
my liking.

Before, the idle speed when cold, was almost 2,000 rpms and when warmed
up was 950 rpms. Now, it is 1200 rpms and 800 rpms respectively. I
picked up 1 mpg more in fuel economy and the transmission shifts far
smoother when going from Park to Drive and Park to Reverse.

Dont know if you want to go to the trouble as i did, but its a simple
permanent cure , doesnt cause any codes to come up, nobody can tell
from the outside of the Device thats its been altered, and has the
benefits as i described above.

Your idle speed is controlled by computer. *Do not* adjust the cable to
hold the throttle open as suggested by another poster. This will result
in other undesireable symptoms and possibly a check engine lamp.

Why do you wish to change the idle speed?

It's currently "idling" at about 2,000rpm which also causes problems with
the gear changing.
In my old car I used to just turn a screw to adjust the idling.

Cheers.

I also miss the days when I could turn a screw to adjust the idle and if
your engine stopped running you could quickly diagnose and fix it.
They're over. Rigging up something to change your idle speed is asking
for trouble. Hyundaitech said it best- it WILL result in other
undesirable symptoms. The reason it idles fast sometimes is to warm it
to operating temperature quickly, saving fuel and reducing pollution.
Turn your radio up and know the computer is doing it's job well.

Ah, then you don't want to change the idle speed, you want to fix the
underlying problem. Yes, there is something wrong if it is idling at 2k
rpm. There can be a lot of reasons for that, such as sticking throttle
linkage, bad sensors, broken vacuum lines, etc.

Intake air temp sensor?
