2003 Ford Ranger Problems

Engine 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.

Hard to Start Cold, Stalling at Idle

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.

Updated Differential Clutch Kit Available if Rear End Noise is Heard

If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing deferential clutch kit. An updated differential clutch kit available.

I HAVE ONLY 48,500 MILES ON MY 2003 RANGER XLT AND I HAVE HAD TO REPLACE CAD.CONVERTER AND NOW UPPER AND LOWER BALL JOINTS. I THINK FORD DID NOT HAVE A GOOD IDEA WITH THIS TRUCK. BALL JOINTS SHOULD LAST 100,000 MILES AND CAD. CONVERTER FOR EVER. I WILL DRIVE HER TILL SHE FALLS APART AND AFTER THAT I AM A CHEVY MAN
This truck has had a transmission leak at 22,000 miles and an oil leak now at 53,000 miles. The brakes are terrible especially the rear. They tend to lock up when cold and wet. I have the 3.0 6 cly and the gas milage is awful. This will be my first and last Ford truck.
For 3.0 engines replace the camshaft position sensor [Part Number: 6B288 (DU-81)] and camshaft camshaft synchronizer [Part Number: DA-2089] every 75K to 90K. This is basic preventative maintenance since these parts are known to go out at that range. If you neglect to do so it will destroy the engine when it fails.
