How to Deal with Intermittent Idle Vibration in Cruze?
2 Answers
The solutions for intermittent idle vibration in Cruze are: 1. Replace the ignition coil or spark plugs; 2. Replace the engine mounts; 3. Clean the engine internally. Idle is a working condition of a car, referring to the engine running in neutral gear. The engine speed during idle is called the idle speed, which can be adjusted by modifying the throttle size, among other methods. Taking the 2018 New Cruze Facelift 320 Manual Pioneer Edition as an example: The manufacturer of this car is SAIC-GM Chevrolet, classified as a compact car, with a naturally aspirated intake form, a maximum horsepower of 114ps, and a maximum torque of 146nm. The dimensions of this car are 4666mm in length, 1807mm in width, and 1460mm in height, with a wheelbase of 2700mm.
I also experienced intermittent idle shaking when driving my Cruze before. It felt like the engine was being lazy, which was particularly annoying. It was mostly due to carbon deposits clogging the cylinder block or throttle body, causing poor air intake, coupled with old spark plugs leading to inaccurate ignition. I tried adding some fuel additive and running on the highway to clear the carbon deposits, but the effect was limited. Later, I went to a repair shop for a thorough throttle body cleaning and replaced the spark plugs, which finally stabilized the situation. I’ve also heard that a dirty fuel filter or a faulty mass airflow sensor can cause similar symptoms, so it’s important to use quality gasoline and perform regular maintenance. If left unchecked, not only will the shaking worsen and fuel consumption increase, but it could also damage the engine’s lifespan. I recommend going to a reputable auto shop for a comprehensive inspection—safety first.
