Hi to all - I have a 2002 XG350 that I purchased new. It now has about 131K on it and has been a relatively trouble free car to this point. A couple of months ago I noticed that the idle was quite high while the car was stommed and in gear. It could probably get to 20 mph without using the accellerator pedal.
I brought the car to the dealer and was told that since there was no code/check engine light, that they couldn't diagnose the problem. I few weeks later there was a check enging light so I brought the car back in. They told me that it needed new ignitiuon coils, and a sensor that controlled the coils. While the car was in I got a call and was told that they also replaced the throttle position sensor. The car runs somewhat better but the problem of the high standing idle is still there, $600. later. Apparently the techs don't know how to adjust the idle.
I'm wondering if anyone has had a similar experience with a huyndai and maybe a solution.
Many thanks, Vic
