The Camshaft position sensor can leak oil into its electrical connector causing the Check Engine light to illuminate. The engine may also stall intermittently as a result.
Check Engine Light and/or Engine Stall
Crankshaft and camshaft position sensors can leak oil into the connector causing Check Engine Light illumination. The engine may also stall as a result. Leaking sensors should be replaced. Certain 2002 models were recalled for a separate camshaft and crankshaft sensor issue. For more information on the recall please click here»
Overheating Due to Stuck Closed Thermostat
The thermostat may become stuck closed, causing an overheating condition. Replacement of the thermostat will be required to correct this concern.
Rattle and/or Check Engine Light Due to Cracked Welds on Catalytic Converter Heat Shield
Welds on the catalytic converter heat shield can corrode causing a rattle during acceleration and possibly causing Check Engine Light illumination. The common repair for this issue is replacement of the catalytic damaged catalytic converter.
Check Engne Light, Misfire, Rough Idle
An engine vacuum leak from the intake manifold gasket may cause the engine to misfire or have a rough idle which may also illuminating the Check Engine Light.
AC Not Cold Due to Pressure Hose Leak
The AC system may blow warm air due to refrigerant loss caused by a leaking low pressure AC hose. These hoses commonly develop a leak at the hose crimp connection.
Knocking Noise From Front Suspension
The front struts can wear prematurely and create a knocking noise when driving over bumps.
Right Side Engine Mount May Wear and Cause Excessive Movement
The engine mount on the right side can wear prematurely and cause excessive engine movement.
Internal Engine Damage Caused by Screws From Intake Manifold
Screws inside the intake manifold can become loose causing internal engine damage if they fall out completely. Our technicians report that using a strong thread locker on the power valve butterfly screws can help prevent them from becoming loose.
Check Engine Light Due to Catalytic Converter Failure
The catalytic converter closest to the cylinder head can fail causing illumination of the Check Engine Light. Prompt repair of this problem is recommended because the catalyst material can be sucked into the engine and cause internal damage.
Check Engine Light/Loss of Power Due to Throttle Body Failure
The electronic throttle actuator (throttle body) can fail causing a loss of power and illumination of the Check Engine Light.
Failed External Seal on Engine Oil Cooler May Leak
The external seal on the engine oil cooler can fail and create an oil leak.
