Have a used 2012 3.5 Ecoboost crew cab with 60,300 miles. Purchased 6 mos. ago with 54,000 miles. Have a 1 year bumper-to-bumper warranty and a 2 year/100,000 year engine warranty. I have experienced the dreaded misfire shutter and loss of power (CAC issue). I am taking the truck next week in for diagnostic to local ford dealership. When I called Ford corp. about this they appeared clueless and did not know what I was talking about. After giving them my VIN, they stated no recall/TSB for particular VIN. Yet after searching not only this site by internet in general there are a few TSBs out there including TSB 14-0017 and 12-10-19. Are TSBs specific to VIN? Also, when the engine light come on (as when I experienced this issue last week), does the truck computer log this so it can be picked up by an OBD II scanner? If I hooked up a OBD II scanner as I was driving the truck would it give me a code that would be helpful to the mechanic? Thanks.
