Guys I noticed a slight vibration in neutral ONLY at 1200rpm. It seems fine in gear. This is a 2010 F 150 with 3k miles. I have noticed that some 5.4 have a viberation out of gear if you rev them up. Maybe this is normal?? Any help Please.. Please any 5.4 owners please chime in thanks..

The dealer told me it was normal it was cam phasers doing it..
