Why does the car intermittently fail to accelerate?

[SanLila]

Intermittent acceleration failure in a car may be caused by fuel system blockage. Here is relevant information: 1. Possible causes: First check whether the fuel filter is clogged, whether the fuel pump pressure is sufficient, and whether the fuel injectors are blocked. If the exhaust system is blocked, inspect whether the three-way catalytic converter and the entire exhaust pipe have any blockages. It may also be due to excessive carbon buildup in the throttle, a faulty idle position sensor, or a damaged air flow meter. 2. Maintenance methods: When driving normally, do not rest your foot on the clutch pedal. While driving, avoid using the clutch in a semi-engaged state. In special cases where semi-engagement is necessary, minimize the duration to prevent burning out the clutch friction plates.
