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. |

'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. |

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. |

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. |

They're > over. I don't miss them at all. Last time I had a car quit on my was my '83 Olds Cutlass with 150,000 miles on it. Last time I had to fiddle with an idle screw was, well, a very long time ago. Overall, the reliability of today's engines and the amount of "tuneup" they need is far superior than anything from the good old days. |
Re: How to change Santa Fe's idle speed ?
Probably not. Air temp is a minor player in fuel management. Coolant temp
is a much more likely cause. |
Re: How to change Santa Fe's idle speed ?
I'm with Edwin. If your idle continues at 2000 RPM anytime other than
immediately after a cold start, there's something wrong that needs to be corrected. You might start by checking for vacuum leaks or, if your check engine lamp is on, having the codes read. |

Today, if your late model car dies, (even if you only run out of gas and burn up the electric fuel pump) you're completely ed. No more looking for a wire or hose that came loose. Just have it towed to a dealership for one of those $1000 fixes (if you're out of warranty)----------HAL |
