Some 2012 Expedition and Navigator vehicles equipped with a 5.4L 3V engine, 6R80 transmission and built on or before 9/21/2011 may exhibit a rolling idle/idle speed variation on cold start. The idle speed could swing up and down by as much as 400 RPM in park or neutral or 150 RPM in drive or reverse typically for 15 to 20 seconds on cold start up.
