Known Problems

Corrosion may develop at the connection between the ignition coil tower and spark plug wire resulting in an engine misfire. The Ignition coil and spark plug wire should both be replaced to correct this condition.

An engine oil leak may develop from the rear of the engine. This is commonly caused by a failed oil pump drive o-ring seal. The leaking o-ring should be replaced to correct this concern.

A weak battery or a burned out brake light bulb may cause the ABS light to illuminate.

The front or rear exhaust manifold may crack causing an exhaust leak. Our technicians tell us the manifold should be replaced to correct this condition.

The timing chain tensioner and guides are prone to wear and may develop an abnormal noise, requiring replacement.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

The engine vacuum hose to the MAP sensor may crack resulting in a vacuum leak causing the engine to run rough and/or stall.

The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

The oxygen sensor can fail causing Check Engine Light illumination and the engine to run rich (burn more fuel than normal).

Front brake rotors can wear causing a pulsation felt in the brake pedal. Our technicians often recommend replacement of the front rotors and brake pads as the best option to correct this condition.

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

Our technicians highly recommend that the engine coolant be replaced every 30,000 miles.

If the ABS light on the instrument panel illuminates, our technicians recommend checking the brake lamps first. It could indicate that a brake light is not working or has burned out.
