What Causes Jerking Sensation During Acceleration?
1 Answers
Acceleration jerking is a sign of issues in the car's system, severe carbon buildup, or poor fuel quality. Below is a detailed analysis of the specific causes: Large spark plug gap: The main components of a car engine's ignition system include the ignition coil and spark plugs. Spark plugs are wearable parts that require regular replacement. As the vehicle's usage time increases, the electrode gap of the spark plugs in the engine will widen. If the electrode gap becomes too large, it can lead to weakened engine power, increased fuel consumption, and reduced operational stability. Severe carbon buildup: Carbon deposits can cause acceleration weakness for three main reasons. The first is carbon buildup on the valves, idle motor, intake tract, combustion chamber, and spark plugs. Cars frequently driven in congested areas, with constant acceleration and deceleration, are prone to feeling sluggish during acceleration. Poor fuel quality: Using low-quality gasoline can affect the fuel filter and fuel lines, leading to poor fuel supply and resulting in weak acceleration. It can also impact the lifespan of the exhaust system's catalytic converter. If the catalytic converter is clogged, it will directly affect the vehicle's acceleration performance, increase fuel consumption, and cause acceleration weakness.
