What is the reason for the buzzing sound when accelerating in a Vios?
1 Answers
Vios accelerates with a buzzing sound due to insufficient oil lubrication and gasoline carbon deposits. The detailed reasons and solutions are as follows: Insufficient oil lubrication: This is because the oil does not fully lubricate all parts of the engine. After running for a while, new oil can uniformly lubricate all parts of the engine. It could also be due to severe wear and tear, followed by cleaning the internal parts of the engine. Running-in for a period of time can solve the issue. Gasoline carbon deposits: When the car's intake and exhaust are not smooth, it may be due to gasoline carbon deposits blocking the intake and exhaust ports, or it could be a filter issue. Cleaning the intake and exhaust ports or replacing the filter can solve the problem.
