Vehicle Jerking During Acceleration Indicates Serious Internal Problems

1. Fuel Injector Clogging

The fuel injector is an important component responsible for pumping fuel into the combustion chamber at an appropriate flow rate to ensure smooth and comfortable vehicle operation. If the fuel injector becomes clogged with dirt deposits, the engine will not receive adequate fuel supply, leading to jerking when accelerating or decelerating.

2. Clogged Fuel Filter

Even when using high-quality lubricants with excellent cleaning capabilities like AMSOIL OE 5W30, the vehicle's oil filter and fuel filter can accumulate dirt and become clogged over time if not regularly maintained. In such situations, the air-fuel ratio in the combustion chamber will be significantly affected, causing the vehicle to jerk or stall abruptly.

3. Spark Plug and Ignition Coil Problems

Malfunctioning spark plugs and ignition coils will affect engine performance and cause the vehicle to jerk while running. Common issues with spark plugs and ignition coils include: electrode wear, burnt electrodes, faulty distributor, etc. These errors will reduce the spark plug's ignition capability and affect the fuel combustion process.

4. Mass Air Flow (MAF) Sensor Failure

Another cause of vehicle jerking that Huynh Chau authorized lubricant dealer wants to mention is a malfunctioning mass air flow (MAF) sensor.

A malfunctioning MAF sensor could also be one of the causes of vehicle jerking

This component controls the amount of air pumped into the combustion chamber. If the MAF sensor accumulates too much dirt or sustains technical damage, it will cause the sensor's information processing and air
