Known Problems

The high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.

Many customers state that whule driving their vehicle, the engine will hesitate, stumble, or lose power. In more severe cases, the EGR valve can be physically damaged. In all cases, the check engine light will be illuminated, and diagnostic trouble codes will be stored in the PCM. 

Diagnosis of the issue has concluded the differential pressure feedback EGR sensor (DPFE) is at fault many times, and incorrectly measures exhaust gas re-circulation (EGR) pressure. 

Correction of the issue requires a diagnostic scan, identification of the faulty sensor, and, ultimately, the sensor and EGR valve may require replacement. In some models, the DPFE sensor is integrated into the EGR valve, and must be replaced together. 

Squeaks and creaks heard while driving over bumps and turning can be caused be a couple common sources and should be carefully diagnosed. Possible weld issues on the lower control arms can cause the noise concerns and require repair kits for the lower control arms from Ford. A jounce bumper (bump stop) rubbing against dry strut plate can cause an abrasion noise from the strut area. In this case the strut assembly should be disassembled to lubricate the jounce bumper and then reinstalled.

The magnet for the camshaft position sensor may fall out of its mount and damage the synchronizers. This causes long crank times when starting the engine and may cause the Check Engine Light to illuminate. If this happens, both the magnets and the synchronizers need to be replaced.

The lug nuts on the Ford Fusion are known to swell to greater than their original size. When these lug nuts swell, the lug nut wrench will no longer fit, so they must be drilled or extracted. 

The lug nuts swell when they have been tightened too tight. To prevent this condition, only tighten the lug nuts with a torque wrench. If changing a flat on the road, the lugs should be loosened and tightened to specification at the earliest opportunity. 

The Ford Explorer is known for a rough idle, engine stalling, loss of power, and misfires, accompanied by the check engine light.

The intake manifold O-ring gaskets commonly leak, which creates a large vacuum leak. This vacuum leak causes unmetered air to enter the engine, and the fuel system becomes insufficient to compensate for the large amount of air reaching the engine. 

Replacing the intake manifold gaskets corrects this concern.

The common problem for ignition misfires are ignition coils going bad. Replacement of the bad ignition coil is necessary. These should be fixed as soon as a problem is detected. Otherwise the misfire can cause damage to other components.

The Ford Expedition has known issues with the V8 engine ejecting spark plugs. This will make a tapping or knocking noise, plus the engine will begin to misfire at all speeds. The check engine light will also illuminate.

The threads on the cylinder head are too short and soft, allowing pressure from combustion to overwhelm and destroy the threads. 

When the spark plug ejects, the cylinder head becomes damaged, necessitating repair of the spark plug port threads, or replacement of the cylinder head and cylinder head gasket. 

Ford has recommended a method of repair for the cylinder head that prevents the spark plug from ejecting under future use. Replacement of all spark plugs is not necessary, but an updated spark plug design can help prevent this from happening in the future. 

There is a technical service bulletin for the V8 engine.

The 1997-2001 Ford Ford Crown Victoria, with a 100% plastic intake manifold, is known for engine overheating, even with normal use, and a coolant leak from the front of the manifold. This will often trigger the check engine light and low engine coolant warning light.

The engine coolant leak is from a factory defect, which causes cracking on the front coolant passage of the intake manifold. In a very short time, this leak will lead to engine overheating issues, especially while the vehicle is idling.   

Between 1999 and 2001, Ford released an updated version of this engine, known as the 'PI' version with a metal coolant passage on the front of the intake manifold, to prevent future issues.

There is no factory authorized repair for the intake manifold, and replacement is required to correct the engine coolant leak and overheating issues.

 

Bulletin 13N02 - This program extends the coverage of the brake booster to ten years of service or 150,000 miles from the warranty start of the vehicle, whichever occurs first. This is a one time repair program.

In some of the affected vehicles, it is possible for the brake booster to develop a small tear in the diaphragm under certain driving and environmental conditions. If this occurs, the driver may hear a hissing noise while depressing the pedal and may also experience a "spongy" pedal feel without a noticeable effect on braking performance. If the vehicle is not serviced, the tear will eventually expand and the pedal effort required to stop the vehicle will gradually increase. However, in all cases, the fundamental vehicle braking system remains functional.

The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.

A rattling noise from the engine may indicate that the timing chain cassette is worn. Our technicians tell us that installing an updated cassette and timing chain tensioner should 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 differential clutch kit. An updated differential clutch kit available.

A defective electronic throttle body (ETB) can cause the Check Engine Light to illuminate and could have limited to no throttle response. Our technicians tall us that replacing the electronic throttle body will commonly correct this concern.
