Me and my wife went to Walmart the car was running fine. Hasn't ran hot, oil fine still with 60% oil life. We were in the store an hour maybe. Come back out and start the car, it is missing very violently and kinda sounds like it's knocking.

Good evening,

Can you upload a video of the car running?

Is the check engine light on? If it is, I need the code to narrow the area of failure.

It could just need a set of spark plugs but need to be sure.
