i have the 2004 f150 - and i have a problem with rough idle am i the only one

 

My 2005 F-150 5.4 Idles rough until warmed up and also the the A/C on. Dealer has checked, but they say it is within normal specs. I think it is the roughest idling vehicle (and most expensive, MSRP $42k) that I have ever had. I have owned 8 other new Ford vehicles and I think I have had more problems with my current F-150 with only $10,000 miles than I have with any other vehicle I have ever owned.
