Hey everyone, I'm new to this side of the forum, I've used the diesel side for my truck but now my wife's expedition is going nuts. We're on vacation in Georgia now, and here's all of what's going on...
1) About 6 months ago, we started hearing an intermittent grinding while accelerating. Reading through the forums, I narrowed it down to the auto locking hub. I replaced the passenger side and the noise went away, then it started to come back, so I ordered another one to do the drivers side (when I get back from vacation.)
2) At random times, after driving for hours or countless miles, you turn the truck off for less than 30 minutes, the truck will fail to start. The wrench icon is displayed, as is the traction control thing, and the message "Service Advancetrac." When you try to start it during this holding time of about 30 minutes, the radio, lights, AC everything comes on but it doesn't even click to try to start.
3) A couple of days ago, while driving back to our hotel following getting stranded in a parking lot because of the awesome "Service Advancetrac," the Service Engine Light comes on, so I run to AutoZone and hook it to their code reader. I get codes P0130, P0150, and P0208.

The more I've tried to research this, the more lost I've become on what it's doing. I've never seen both O2 sensors go bad simultaneously, and with the code now on Cylinder 8 injector, I feel like it's leaning toward the battery going bad and not holding a full charge. Oh, and since I forgot to mention it, it's a 2011 Ford Expedition XLT 4wd with 179k on it. Please help, I'm scratching my head a lot on this one.

 

You are right on both being bad....usually it's just one. Not up to snuff on mine yet but my bet is one with fix the o2 problwm.
