'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.'
REPLY: Not according to my local Hyundai Dealerships Service Dept ;
they said 2000 rpms upon a cold start is how it comes from the factory
and no external anomoly is causing it.
But there is a difference between start up and normal idling. He did not
mention it was only at starup, but did give the impression it was constant.
Perhaps clarification is needed.
