The engine may stall at times due to a failed crankshaft position sensor and/or camshaft position sensor, These sensors can fail intermittently as they warm with the engine. Sensors on certain models have been recalled by Nissan and will be replaced as necessary. Please visit our recall section for this model to see if your vehicle is covered by this recall.

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.

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 damaged catalytic converter.

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»

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.

The camshaft driven distributor can leak oil and cause a malfunction of the crankshaft position sensor. The engine may crank but not start or run very poorly.

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.

The thermostat may become stuck closed, causing an overheating condition. Replacement of the thermostat will be required to correct this concern.

The ground inside mass air flow (MAF) sensor can corrode and possibly cause drivability problems. The corrosion is enough to affect the sensor data but not enough to create a trouble code. Diagnosing this can be difficult because it won't always illuminate the Check Engine light.

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.

The front struts can wear prematurely and create a knocking noise when driving over bumps.

The engine mount on the right side can wear prematurely and cause excessive engine movement.

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.
