What are the symptoms of a clogged fuel filter in a car?

[VivianAnn]

Symptoms of a clogged fuel filter in a car include jerking movements, engine shaking at idle, poor acceleration, and difficulty under load. Below are the reasons for these symptoms: 1. Jerking movements: If the fuel filter is clogged, insufficient fuel supply can lead to poor gasoline atomization, resulting in incomplete combustion of the air-fuel mixture, which easily causes jerking movements. 2. Engine shaking at idle: If the fuel filter is clogged, the engine's fuel supply will be disrupted, and the fuel injectors will have poor atomization, causing noticeable shaking when the engine is at idle. 3. Poor acceleration and difficulty under load: If the fuel filter is clogged, the engine's power output will decrease, leading to poor acceleration, which is especially noticeable when going uphill or under load.
