Default 2016 chrysler 300 running rough. Check engine light is on all the time.

The wife filled up yesterday. Drove fine. This morning she gets in to goto the store and its running rough. Check engine light is on solid and the interior lights are pulsing. Looking at the battery voltage, it is 14.3 at idle. It only has 37000 miles on it. Any ideas ??

The gas station is a flash/circle k. Pretty new gas station but i find it very odd that it ran fine after fill up and get in next morning and it does this. Will check the codes today.

I asked her that very question. She said know. She makes sure to pull up to a pump that doesnt have a green nozzle. But there have been instances where the delivery driver has put diesel into a gas storage tank.
