Why does the Buick Excelle not respond when stepping on the accelerator?

[Rosalie]

It should be a problem with the transmission. Electronic throttle accelerator: The electronic throttle accelerator makes the throttle response more sensitive and provides faster acceleration. Since power is directly proportional to fuel consumption, it will relatively consume a bit more fuel. No load on the car: No load on the car. The electronic throttle accelerator does not modify the car's circuit or fuel system, so it will not impose any load on the car. It can be said to cause zero damage to the car. Regular use of the accelerator can also reduce engine carbon deposits. Modern accelerators are quite intelligent, allowing you to adjust the speed as desired—faster or slower—without any issues regardless of the road conditions.
