Known Problems

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.

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.

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.

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.

The temperature gauge on the instrument panel may fluctuate and give incorrect readings. If this happens, a new gauge and sender kit should be installed. The sending unit "sends" the information to the gauge.

If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.

If oil is leaking from the gaskets and seals, the engine needs to be resealed.

The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.
