Why does the Corolla shake when in neutral?
1 Answers
The reasons why the Corolla shakes when in neutral are as follows: Dirty throttle body and excessive carbon deposits in the fuel injectors: After driving for a certain mileage, a dirty throttle body can cause the throttle to not close properly or the idle stepper motor to get stuck, both of which can result in excessively high engine idle speed. Additionally, carbon deposits generated during engine operation can also cause the vehicle to shake, especially when starting the engine. The engine may shake more than usual, and in some cases, it may not start on the first attempt. Aged engine mounts: Sometimes, car shaking is related to aging engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and the interior of the car, causing shaking at idle. The car engine is most prone to shaking when the electrical system is turned on while the engine is idling. Aged, deformed, or bulging tires: Shaking during vehicle movement is mostly related to the drivetrain, with tire issues being the most basic cause. If the owner suspects that the shaking during driving is due to tire problems, the simplest method is to carefully feel the tire tread with their hand. If the tread appears jagged, it indicates that the tires have aged or deformed.
