Why does my 01 sportage idle high with the heat on

Hello, That is insanely high. I would also be concerned. This one is going to take hands-on testing, as this is not a common issue ... at all. Suffice to say that there is likely an electrical issue somewhere, possibly in the powertrain control module (PCM).
