A/F ratios being off is a tuner issue. If the tune was ran too long with A/F's off, then that could cause the #8 to fail. If the mechanic was truly scared about an A/F problem, he should immediately to a compression check of the cylinder. This will tell you if it has failed or is about to fail. If the PCM has been flashed, you are going to have a rough time at various Ford dealerships getting it covered under any type of warranty, if one still exists on your 2011. Sorry to hear this is happening. I know first hand.
