Bronco 2.7L issues - CEL codes and airbag warning light

[Rex21c]

While I have no idea what the dealer filled it up with before I took delivery, I have put 91 in it both times I have filled it up.

Edit. I also wanted to mention that I have never noticed it running bad, but I will say that the other day I went to leave for work and I opened the garage door, walked over to the bronco, started it and drove away within about 20 seconds, and closed the door as soon as I was clear. One of my daughters complained the garage stunk like gas just over two hours later. Also, my fuel mileage running on eco mode is hanging out around 15.8 as read on the trip display. That is pretty much what my F150 gets with its 4.6L running on 35s. I expected a bit better from the Bronco.

Any update on the codes or a resolution?

I'm hoping it was another misaligned air filter issue.

Sorry, the tech said the pin point test pointed to both rear O2 sensors being bad. They replaced them, cleared the codes and all has been well since. Also to note, I have a 35 mile one way drive to work, and the bronco has been averaging 20mpg.

Very cool, glad a resolution was found. Good to know on the MPG as well.
