What causes engine shaking at idle?
1 Answers
The reasons for engine shaking at idle are as follows: 1. Fuel quality issues: The shaking may be caused by fuel quality problems, such as using gasoline with a lower octane rating than recommended or poor-quality gasoline, which can lead to idle shaking. If this problem occurs immediately after refueling, it is most likely due to fuel quality issues. In this case, it is necessary to go to a 4S shop for inspection and repair to see if the engine has been damaged. 2. Spark plug issues: Aging, damage, or malfunction of spark plugs can also cause idle shaking. For example, excessive carbon buildup on spark plugs can be resolved by replacing them with a new set, and the shaking problem will disappear.
