What are the reasons for the Buick Excelle's inability to accelerate?

[McEloise]

Buick Excelle's inability to accelerate when stepping on the gas pedal may be due to excessive engine oil, overly viscous engine oil, malfunctioning sensors around the engine, or faults in the transmission system. Below is a partial introduction about the gas and brake pedals: 1. Gas pedal: The gas pedal, also known as the accelerator pedal, is part of the car's fuel supply system. By controlling the amount of pedal depression, it regulates the throttle opening of the engine, controls the intake air volume, and the computer adjusts the fuel amount, thereby controlling the engine's speed. 2. Brake pedal: The brake pedal is the pedal that limits power, i.e., the pedal of the foot brake (service brake), used for deceleration and stopping. It is one of the five major operating components in car driving, with very high frequency of use. How the driver controls it directly affects driving safety. Brake pedal operations include: gradual braking (i.e., anticipatory braking), emergency braking, combined braking, and intermittent braking.
