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
