Have a 2016 Jeep Grand Cherokee with 63k miles on it, like 4 momths ago it picked up a P0440 and a P0456 which are with the Evap system, havent donde anything since its not really something to worry about, its not the cap because its an open container. However in a span of those 4 months sometimes in the morning when im on my way to work, two times when decelerating it shut of but it only happened in really low speed, today happened again but it didn’t shut off, it just jerked like it was going to but I accelerated and it went completely fine after that. I dont have any misfire codes or it doesn’t have any misfire i general, what the heck could that be?
