What causes a gasoline engine to fail to accelerate?
1 Answers
Reasons why a gasoline engine fails to accelerate: Fuel system blockage: First, check if the fuel filter is clogged, whether the fuel pump pressure is sufficient, and if the fuel injectors are blocked. Exhaust system blockage: Inspect the catalytic converter and the entire exhaust pipe for any blockages. Excessive carbon buildup in the throttle body: Idle position sensor or air flow meter damage. If the car cannot accelerate normally during driving, it is recommended to visit a 4S shop for computer diagnostics to identify the fault storage code. If the issue is not related to the electrical components, then it may be a mechanical problem, which can be disassembled and inspected by a professional technician. 4S shops have specialized equipment for this purpose.
