Known Problems

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.

The idler arm or pitman arm in the front suspension may wear causing excess play in the steering and front end alignment problems.

A burning smell may develop due to an oil leak form one or both valve cover gaskets. Resealing the valve cover will generally correct this concern. However, the valve covers should be inspected and replaced if damaged.

An engine vacuum leak may develop from the throttle body gasket causing a higher than normal idle speed. Failed gaskets should be replaced.

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 vacuum release actuator for the parking brake may fail, preventing the parking brake from releasing automatically. Our technicians remind us that there is a mechanical release lever on the park brake ratchet you may use if the park brake does not release automatically. (Care should be taken when manually releasing the park brake!)

    The engine control module (ECM) electrical grounds on the front of the engine block may develop high resistance causing engine performance issues.

    The EGR system control solenoid or valve may fail causing the check engine (SES) light to illiminate. Engine pinging on acceleration may also be noted if the EGR system fails.

    Excessive carbon build up in the engine combustion chambers may be the cause of a smog check failure due to excess NOx emissions. A "top engine" decoarbonization cleaning procedure will commonly correct this concern.

    A worn bushing in the transmission could cause a transmission fluid leak from the axle seals. The transmission must be disassembled and the bushing replaced to properly correct this leak.

    The torque converter clutch (TTC) may stop working due to an internal transmission failure. The Check Engine Light will illuminate if this occurs. Our technicians tell us the transmission will require dis-assembly to correct this concern.

    The engine control module (ECM) electrical grounds on the front of the engine block may have high resistance causing a rough running engine or stalling condition.

    The fuel injectors may short out electrically causing a rough idle.

    The alternator may fail causing the battery to go dead or the engine to stall while driving.
