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.
The engine may have a higher that normal idle at times. After cold start with an automatic transmission and when the clutch is depressed with a manual transmission. Our technicians tell us updated powertrain control module (PCM) software is available to address this concern.
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.
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 synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.

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.
A buzzing type noise may be noted from upper engine area at about 1900 RPM, under light acceleration. Our technicians tell us this can be caused by loose ignition coil bracket bolts. Coil bracket bolts should be checked for the correct torque before further diagnoses is performed.
Moisture inside the rear brake drum assemblies can cause the rear drum brakes to grab, or lock when first driving. Inspect the rear brakes, replace the rear shoes as needed, and make any adjustments. The back side of the backing plate needs to be sealed where moisture can get into the drums to prevent this from recurring.
Noisy engagement of clutch slave cylinder to the pressure plate can cause a squeak noise when pressing and releasing the clutch. Replacement of the clutch disc, pressure plate, clutch slave cylinder, plus the application of a special metal assembly paste to the mating components will be needed to reduce the noise.
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.
