I have a 2008 MKX, does anybody have a problem with the idle after warm up when sitting at a traffic light I feel vibrations in
the steering wheel, very annoying.
RPM checked by the dealer is 600, they ran all the checks & found nothing wrong. If I feather it up to 700-750 RPM it goes away.
The dealer said they can not up the idle that is all set by the computer.
I went to the dealer the other & test drove a 2009 model no problem & the idle was 750 on the tach.
Please advise if any body has had a similar problem or any fix to my problem.
