Known Problems

The fuel pump may fail causing engine to stall and not restart.

The water pump may develop a coolant leak resulting in an engine overheating condition.

 

Fuel injectors can short-circuit electrically causing a rougher than normal idle and reduced performance.

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

Body: A dirty throttle body may cause a lower than normal engine idle resulting in a stalling condition. A stalling condition may also result if an idle learn procedure is not performed if the battery goes dead or is disconnected.

The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.

One or more power windows may stop working due to a failed window motor or switch. Proper diagnoses will be necessary to determine the exact cause.

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. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

Air flow from the dash vents may be incorrect due to a damaged engine vacuum hose near the battery tray.

A stalling issue may occur if the battery goes dead or is disconnected and the "idle learn" procedure is not performed. For more information on "relearning" the engine idle speed, please click here»

An engine oil leak may develop from the oil pump drive O-ring. This can often be confused with an intake manifold gasket leak. Careful inspection is required to determine the exact cause of the leak. Replacement of the failed 0-ring will commonly correct this concern.

The ignition module or crankshaft position sensor may fail causing the engine to die and not restart. Diagnoses will be necessary to determine if the module or crank sensor is causing the no start condition.

The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
