    Today, I ran an errand around 1pm and came back around 2pm.

    Went outside around 7:30pm and hear this strange humming noise coming from the center area of my truck. I went back in the house and got my keys and when I walked back out, it had stopped. I started it up ..No issues.

    2013 4cyl. Double cab...67k miles

    I will check again soon . Any idea what this could be?

    Don't know about newer Tacos but our 2018 4Runner 4.0 does exactly this and it's totally normal, some kind of vapor purge in the gas tank or something. :thumbsup:
