2015 Chrysler 200 code 3

Hi! This is Bo with Car Genius at RepairPal! Spitting and sputtering is no good! the code 3 leads me to think it's a P0303 which is a mis-fire code. I'd get it checked right away and recommend not driving it. It won't necessarily hurt the engine but it is allowing raw fuel throug ht engine to the catalytic converter and that can cause some serious and expensive damage! If you have any other questions feel free to give us a call at 877-913-1554! We'll be happy to help or find you a certified shop in your area!
