2012 idle speed

Seems to me the idle speed is a little low and I don`t know if there is any simple way to kick it up. On a cold start it goes to like 12-1300 rpm, then settles in after a bit of warm up to around 750. When it is hot it is at about 600 and if I don`t blip the throttle and just ease out the clutch it will easily die. I drive 2 other stick shift cars and have for 40 years...is it just me???

Well I don't have a 12 but, I think 600-700 is normal. The jeep will up the idle during cold starts to get the oil flowing.
Settle down some to around 700.

It should not die though.

I would bring it back to the dealer
