Why is my Chevy Cruze shaking at idle?

Why is my Chevy Cruze shaking at idle?
There can be several reasons why your Chevy Cruze is shaking at idle. Here are some possible causes:
1. Spark Plugs: Worn or faulty spark plugs are one of the most common causes of vibrations and shaking at idle in the Chevy Cruze. Even though most modern vehicles use iridium spark plugs that have a longer lifespan, they still need to be changed at the recommended intervals.
2. Oxygen Sensor: If the oxygen sensor in your Cruze begins to fail, it can cause the engine to run too lean or too rich. A super lean running engine can often result in shaking at idle. However, the shaking may decrease as the engine speed increases.
3. Harmonic Balancer: A failing harmonic balancer can also cause your Chevy Cruze to vibrate at idle speed. As the crankshaft spins faster, the vibration may become less pronounced.
4. Vacuum Leak: A vacuum leak can introduce excess air into the intake manifold, causing the engine to run rough and shake at idle. Vacuum leaks can occur due to issues with vacuum hoses or gaskets.
5. Ignition Coil: A faulty ignition coil can lead to misfires in the engine, resulting in rough idling and vibrations. If the ignition coil is not functioning properly, it may need to be replaced.
It’s important to note that these are just some of the possible causes, and a proper diagnosis by a qualified mechanic is recommended to accurately identify and address the issue with your Chevy Cruze.
