I posted this before and with the hot weather all was good. Last year I took the car in for the cat recall and they did updates. When you started the car after it sat overnight the idle would go up to almost 3000 rpm's. Never did it before till the update was done. During the hot summer now it was fine, rpm's went to 2000. Now the last 2 mornings have been around 45 degrees and yes, back up to 3000 rpm's. I notified Kia last year and they had no help and dealer is pretty much useless. Dealer told me Kia has a high idle problem and can't figure it out. Kia says they are unaware. Well back to calling Kia next week. Thanks ahead if anyone has any ideas or thoughts.
