Known Problems

The throttle position sensor (TPS) may fail. Common symptoms of a defective TPS can be rough idle, hard starting, hesitation on acceleration, poor fuel economy, and stalling.

Catalytic converter failure is common. Internal components become loose, causing a rattle or creating back pressure in the exhaust.

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

The illumination of the Check Engine Light is common due to ignition misfire, often caused by bad spark plugs or ignition coil.

Transmission wear is common. Pieces of broken components are often discovered in the transmission oil pan when the transmission is serviced.
