Question...idle problem?

[ltd1837]

I bought a 2004 Sante Fe 1 month ago...I absolutely love the car (when I get to drive it...my 19 yr old daughter is home from college and drives it more than I do). I've noticed that when sitting at a light or in traffic after coming to a full stop the car "bucks" a little...first time it happened I thought that someone hit me in the rear. The service department is telling me that they can't find anything wrong with it...anyone else have this problem or any suggestions what I can tell the service guys (nicely please...lol)

Wish i could help but im just getting into the Hyundai thing[Still ford guy] I can say that if i 3/4 throttle my 01 when it shifts into second it will die for a mega second and pic back up.
Did you try unhooking the battery and hook it back up after a minute to see if clearing it will help. Im sure some on here can help

I suspect the drive-by-wire electronic throttle..

I Hate these thing's and they can have effect's on the car when a glitch happen's,
