2003 Ford Ranger ProblemsEngine Buck/Misfire at Freeway Speeds
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.
Bogging, hesitation or stalling may be experienced during moderate to heavy acceleration. This can be caused by a failing of many sensors or modules in the fuel injection system. It is recommended to have an experienced shop perform diagnosis to find the root of the problem.
If you experience cold starting problems, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steadily and run when the accelerator pedal is not pressed.
