I haven’t seen anyone mention this before so I thought I would put this out there.
I have a ‘22 Badlands 2.3L 7MT with 21k mikes in it. I do have Sport mode enabled via ForeScan. Recently when I am in Sport mode if I do a hard acceleration in 1st gear and get the RPMs up to 3.8ish I will get a backfire. It doesn’t do it every time but usually in the first few minutes of driving.
it just started doing this so I don’t have many details on when it does versus when it doesn’t backfire, only that it takes a hard acceleration and high RPMs.

Backfire is rich air/fuel, makes sense you're seeing it on a cold start at WOT in sport though but would think the computer would catch it.

Either take it in to the dealer to look at it or modify your morning routine with a good warm up period before hitting the redline.

Are you sure it’s a backfire and not a misfire?

What he said. All EFI vehicles have a routine on startup. It'll run rich to protect the motor. You shouldn't be pushing a vehicle that hard until it's fully warmed up. Your backfire is driver error, not truck error.

I can accept driver’s error. (y)

it just got cold in texas, so the cold start fuel compensation is much higher than it has been when the weather was warmer. Also its not a great idea to run the motor hard before its warmed up.

The 2.3L in the focus RS back fires. But the Bronco probably shouldn't. I have heard some broncos with the 2.3 with a slight burble maybe to make it sound a little more mean, of they may have had an exhaust.

With the MRT Trail Rated Axleback, I get a ton of burble in winter running Normal Mode. Even a few little pops/backfires till it warms up.

If you are quick to clutch in(especially while cold) the engine hasn’t scavenged its cylinders fully, additionally it’s running a richer AFR… Sport mode will further increase the audibles due to the mapping on throttle lift off (cancelling the revhang/scavenging)

Add all of this up together and you’ll find a bit of extra noise comin out the tail pipe
