Rough idle in F150 4.6 2002 Ford Dealer says Normal cant fix

Well, changing the idle will not help. I can feel it up to at least 2000 rpm when not in gear. It still has the slight miss/vibration even if I slowly rev the engine unloaded up to at least 2000 rpm. It is either tuned extremely lean or something is trying to wait another 6,000 miles to mess up after the warranty is gone.
