Banging/Misfire when starting the car?

[GreenenvyFiST]

2014 with approx 50k miles. Stock engine wise. I took a drive from San Antonio to D/FW to see family, and I drove it between 75-80 in 4-6 gears most of the time. I stopped to use the bathroom and when I started it up, it made a weird noise like a misfire type bang noise just when it starts. I got to the family home and let it cool overnight, but it still does it. Not sure if I should be worried.

No engine light

My spark plugs back out all the time and I have to retorque them. It causes that among other things. Might check and make sure they’re torqued correctly. Edit: or replace them if they have 50k miles on them.

Tune+ suggested 13ft lbs so I went with that.

Also, the blend door click is not the noise lol. I've had that for a long time.

suggest starting it with the hood open and watching for movement of the engine

Beat me to it.

Update: Car makes what sounds like a mini backfire noise in low gear 1st or 2nd. If I hit the gas there is an audible pop/bang noise and feel( reminds me of one of those tunes).

Soooo, have you inspected your motor mounts yet?

I tried to move the motor around and seemed solid, no excessive movement. Haven't had time to take them out.
