What causes a scooter to sputter and fail to accelerate when the throttle is applied?
1 Answers
Main reasons why a car fails to accelerate when the throttle is pressed: 1. Ignition system failure: The throttle position sensor signal is actually part of the intake system. For the engine to function properly, it requires sufficient air. If there is a leak or blockage in the intake system, symptoms such as reduced power, inability to increase RPM, and vehicle shaking may occur when the throttle is applied. 2. Fuel system blockage: The engine's fuel system is also crucial. If low-quality gasoline is used, it can lead to issues such as fuel pump burnout, catalytic converter failure, or piston problems, directly affecting engine performance. This can result in engine stalling or failure to accelerate.
