Ford Will Service Some F-150s, Expeditions, And Navigators For Rough Idle

June 25, 2014

Ford has found a problem with some 2004-2010 F-150 and 2006-2008 Lincoln Mark LT pickup trucks, and the 2005-2013 Expedition and Lincoln Navigator SUVs, all equipped with 5.4-liter V-8 engines.

The vehicles in question may exhibit intermittent rough idle, and/or a rattle noise while driving accompanied by a lit check engine light on the dash. Ford engineers have nailed the problem down to faulty cam-timing solenoids.

These solenoids control camshaft timing, allowing the engine to operate at peak power and efficiency at all times. When they go bad, camshaft timing can go off, causing drivability and emission issues.

The fix

On affected vehicles, Ford dealers will replace both the left and right solenoids. Ford is managing this TSB by VIN (Vehicle Identification Number) and warranty coverage applies for vehicles under the new car warranty. Some vehicles outside the new car warranty may be covered under the emissions warranty, or if the vehicle is covered under an extended service plan, it might cover this repair.

This repair is labor-intensive and can take up to four hours, so plan on leaving the vehicle for the day to have this service performed.
