Symptoms of a faulty vacuum booster pump in a car: It can cause heavy steering and abnormal steering noises. The larger the steering angle at low speeds, the louder the noise. The metal particles from the worn-out booster pump can damage the steering gear, and cleaning the pipelines is also troublesome, with the possibility of needing replacement. Additional information: 1. Meaning of the booster pump: The car booster pump refers to a component that helps improve and stabilize car performance. It mainly assists the driver in adjusting the car's direction. Currently, most cars are equipped with booster pumps, mainly including the steering booster pump and the brake vacuum booster pump. 2. Classification of booster pumps: In the current market, power steering systems can be roughly divided into three categories: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. In the mechanical hydraulic power steering system, the amount of assistance is only related to the increment of the steering wheel angle (angular velocity).

Why does the Nissan Paladin idle shake?

Nissan Paladin idle shaking may be caused by severe engine carbon deposits or unstable oil pressure. Severe engine carbon deposits: When there is excessive carbon buildup, the gasoline sprayed by the cold start injector can be largely absorbed by the carbon deposits, resulting in an overly lean mixture during cold starts. This makes starting difficult. After the engine starts, the gasoline adsorbed on the carbon deposits is then sucked into the cylinder by the engine's vacuum and burned, making the mixture too rich. The engine's combustible mixture alternates between being too lean and too rich, causing idle shaking after a cold start. Unstable oil pressure: If the fuel pump's supply pressure is abnormal or if the intake pressure sensor values are incorrect or malfunctioning, it can cause the vehicle to shake. The solution is to check the oil pressure and replace components if necessary.
