Rough start !
Hello all. I have a 2006 Kia sedona auto transmission van. It was pretty cold outside and I started the car but it started pretty rough. I heard a knocking noise and accelerator didn't respond. Check engine and ESC OFF lights came on. I shut it off started again knocking noise was gone but it was still running rough. After5 min I shut it off and restarted again and it was fine. The check engine light is still on.I got scared when I heard the knocking noise. I will take it to a mechanic tomorrow but please help me with your ideas. Thank you.
