My 2013 Hemi has 27000 miles on the clock...it just now started idling a little high randomly at start up. It has always idled at maybe 1200rpm at start up and then drop to 900 after a minute or so but the last few days, it will start fine an idle at 1200rpm and then climb to 1500rpm and then back to 1200rpm and finally down to the normal 900rpm. It has never fluctuated like that before...cold weather, hot weather...always the same start up. That is why this minor fluctuation is concerning me. No codes of any kind!
