Model Years Affected: 1999, 2000, 2001, 2002, 2003

Engines Affected: 2.3L 4 Cylinder, 2.5L 4 Cylinder, 3.0L V6, 4.0L V6

Average Mileage: 126,342 mi (11,300 mi - 271,000 mi)

Verified

The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.

    once you hit around 45 to 50 mph, the truck will shift into overdrive and the rpms will drop from 2500 to 1800...then you feel the truck start to buck or jump or miss..
