Signs of car engine problems, often overlooked by users

The engine of a car is considered the "heart", contributing significantly to the vehicle's efficient and smooth operation. Therefore, users should regularly check and maintain it periodically to ensure stable and safe engine operation. There are many easily recognizable signs that the car's engine is having problems or errors, but users often "ignore" or lack the knowledge to recognize it, causing serious damage in the long run, costing a lot of money in repairs.

The article below shares some common signs that indicate a car engine is having problems that car users should pay attention to:

Engine warning light (goldfish error)

The most obvious sign that your car's engine is having trouble is when the check engine light comes on on your dashboard or instrument panel. It's a signal that your car's sensors have detected a problem, from something as minor as a loose gas cap to something as serious as a malfunctioning exhaust system.

Ignoring this warning light can lead to more serious damage and higher repair costs. Some users who lack knowledge and understanding often do not pay attention and ignore this warning light, leading to more serious damage in the long run. Repairing engine-related damage is often very expensive and difficult to restore the engine's original performance. Therefore, when encountering an engine error light, users should take the vehicle to a reputable service workshop or garage for inspection and repair.

Strange colored smoke from exhaust pipe

White smoke from the exhaust is a telltale sign that something is wrong with your engine. White smoke usually occurs when coolant enters the combustion chamber, which can cause engine damage if not addressed promptly. Blue smoke, on the other hand, indicates that engine oil is being burned in the combustion chamber, possibly due to worn or mushy piston rings or gaskets.

Black smoke indicates that the engine is burning too much fuel, possibly due to a problem with the fuel system or ignition system. Any color of smoke should be checked immediately to ensure the engine is running properly.

Strange sound from engine

When the engine makes a knocking, screeching or banging noise, this could be a sign of a serious problem inside the engine such as damaged pistons, connecting rods or cylinder bores.

These sounds should never be ignored by the user because they signal the need to repair or replace important parts inside the engine. Strange engine sounds are an early warning sign, helping the driver to detect and fix problems before they become more serious.

The car accelerates weakly and loses power when stepping on the gas pedal.

Abnormal acceleration or signs of loss of power when pressing the gas pedal also indicate that some details related to the car engine may be damaged. If it is only minor damage related to dirty fuel filter, clogged fuel system, dirty engine air filter, dust or ineffective spark plug system, repair and replacement will be simple and inexpensive.

However, serious damage to internal engine components such as pistons, cylinders or valve systems, etc. will be very expensive to repair. Loss of power not only affects driving performance but can also be dangerous in situations requiring rapid acceleration.

Idle mode vibrates strongly

If the vehicle vibrates violently when the engine is idling, it indicates a problem with the ignition system, spark plugs, or fuel system. These vibrations are not only uncomfortable to drive, but can also be a sign of damage to internal engine components. When the vehicle vibrates abnormally, it is necessary to have the vehicle inspected and maintained to ensure safety.
