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.

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.
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.
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.
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.
