Truck Engine Hesitation: Causes and Solutions

Anh Tuan, a seasoned truck driver in Hanoi, specializes in transporting construction materials from Gia Lam to inner-city projects. Recently, his beloved Dongfeng truck started experiencing engine hesitation when accelerating.

“Yesterday, while carrying bricks to a construction site in Hoan Kiem, the traffic was heavy. Every time the light turned green, the truck would stutter and struggle, almost stalling. The cars behind me honked relentlessly, it was so embarrassing!” Anh Tuan complained to a fellow driver while having tea at a roadside stall in Minh Khai.

So, what is engine hesitation? What causes it and how can it be fixed? Let’s delve into the details with XE TẢI HÀ NỘI in this article.

What is Engine Hesitation?

“Engine hesitation” refers to the phenomenon where a vehicle experiences sluggishness, jerking, and a lack of power when the driver accelerates, especially when the truck is heavily loaded or moving at low speeds. This not only causes discomfort and affects the vehicle’s performance but also poses significant road safety risks.

Causes of Engine Hesitation

There are numerous reasons why a truck might experience engine hesitation. Here are some of the most common causes:

• Weak or faulty fuel pump: The fuel pump is responsible for supplying fuel to the engine. If the pump is weak or malfunctioning, insufficient fuel supply will cause the engine to hesitate, especially during acceleration.
• Clogged fuel filter: The fuel filter removes dirt and debris from the fuel. When the filter is clogged, fuel flow is restricted, reducing the amount of fuel delivered to the engine.
• Weak spark plugs: Weak or inconsistent spark plugs can also contribute to engine hesitation.
• Faulty exhaust gas sensor or oxygen sensor: These sensors provide information about exhaust gas and oxygen levels to the engine control unit. When a sensor malfunctions, the control unit cannot adjust the air-fuel mixture accurately, leading to hesitation and jerking.

In addition, engine hesitation can also be caused by other factors such as a stuck EGR valve, leaks in the intake manifold, or clogged fuel injectors.

How to Fix Truck Engine Hesitation

To effectively resolve engine hesitation, it’s recommended to take your truck to a reputable garage for inspection and repair by experienced technicians.

Here are some common solutions:

• Clean or replace the fuel pump: If the fuel pump is weak or damaged, cleaning or replacement is necessary to ensure adequate fuel supply to the engine.
• Replace the fuel filter: Regularly replace the fuel filter according to the manufacturer’s recommendations to maintain clean fuel.
• Inspect and replace spark plugs: Weak spark plugs should be inspected and replaced to ensure efficient fuel combustion.
• Inspect and replace sensors: If a sensor is found to be faulty, replace it to ensure the engine control unit functions correctly.
