Its a PITA, but you just gotta drive the car. Dont worry about drive cycle parameters, just drive. A long road trip should help.
I've done plenty of searches. If the car had an aftermarket tune this would be an open and shut case.. the car is stock and I've tried many of the suggested fixes
300+
A long road trip won't help. I go through this every year lately. The only "fix" is city/town driving. Mine failed inspection yet again this past Saturday and again today. I went for a long road trip out to the mountains and back on Saturday, well over 200 miles round trip.
Do you guys disconnect the battery when the car is in storage?
no, but do have it on a battery tender.
300 miles should be way more than enough. I had same issues with my 2010 supercharged Roush, but it turned out the monitors had been turned off in the tune.
OP can you get local tuner to just look at (inside) your tune and confirm the monitors are on? That might be worth confirming.
Once my monitors were turned on, it took around 40 miles (or less) of driving to reset all mine except EVAP. But then one more short drive and a day or two sitting, and the EVAP reset itself too.
A local guy I talked to said that Fords reset monitors pretty quickly, so 300 miles is wayyyyyyy more than necessary. There are some specific drive cycle requirements that should be followed, such as: http://www.obdii.com/drivecycleford.html

According to OP the tune is stock. That being the case, its been known the stock monitors are a PITA to set. Im delaying my header install so that as I get near the time to start getting my emissions check in AZ, Ill have plenty of time to get the monitors squared away.
Ill eventually get the cats made for use with the Dynatech headers. For now, its easier for me to leave the logs in and use the stock cat midpipe.
Yes, I saw that, but you just never know what's going on. It can't hurt to simply confirm they are indeed turned on.
Didn't take me more than 75mi, to set mine. I followed the repair manual to a tee though.
3/4 tank+ really matters too!
