Lower intake manifold failure

The lower intake manifold gaskets can also deteriorate, leading to coolant and oil mixing.

Fuel injector issues

The fuel injectors can become clogged or fail over time, causing misfires and rough engine performance.

Crankshaft position sensor failure

This sensor can fail, leading to stalling, no-start conditions, or erratic engine behavior.

Egr valve problems

The Exhaust Gas Recirculation (EGR) valve can become clogged or fail, causing rough idling and poor engine performance.

Spark plug wire wear

The spark plug wires can wear out, leading to misfires and reduced engine efficiency.

Supercharger issues

If equipped with a supercharger, it can develop bearing or coupler wear, leading to noise and performance issues.

Coolant elbow failure

The plastic coolant elbows can crack and leak, leading to overheating.

Idle air control valve failure

This valve can become dirty or fail, causing erratic idle speeds or stalling.
