Paint aging, corrosion, and chassis erosion. The specific details are as follows: 1. A car rots from the bottom up: The chassis is the part closest to the ground and is severely affected by road conditions. Many cars, when lifted for maintenance, reveal rusted and corroded underbodies, with wheel wells even loosened or perforated. The main culprit is the corrosive nature of acid rain. 2. Erosion by acid rain: During summer thunderstorms with heavy rain and strong winds, vehicles parked outdoors not only face challenges to their paint but also suffer from acid rain erosion on the chassis. Additionally, thunderstorms cause road flooding, and after driving through water, acidic rainwater remains on the chassis. 3. Acid rain lingering on the chassis causes rust: Moreover, this acidic rainwater and vapor can seep into the car body through tiny chassis pores, affecting many components of the vehicle.

What Causes the Abnormal Noise When Accelerating?

The causes of abnormal noise when accelerating are as follows: Abnormal noise from the fuel pump motor: When there is wear or impurities inside the fuel pump motor, abnormal noise will occur when accelerating. This issue requires replacing the fuel pump. Abnormal noise from the throttle: Modern throttles are electronic, and the motor controls the opening and closing of the throttle. When the motor gears are worn, insufficient engagement can cause abnormal noise. Excessive carbon deposits or sludge in the throttle can also lead to abnormal noise. The throttle can be cleaned, but if the motor is damaged, the throttle needs to be disassembled to replace the servo motor. If there is abnormal noise when accelerating, first check if the dashboard or workbench is loose, then inspect the transmission. Oil contamination inside the transmission can cause abnormal noise from the transmission oil pump.
