7 Signs of a Failing Engine Infographic

The engine is a crucial component of your car, translating energy from the fuel into mechanical power. Depending on your vehicle type, petrol, diesel, or liquid petroleum gas (LPG) can energize and propel it forward.

Driving can be extremely difficult to manage if your engine has issues, causing numerous problems and raising costly repair bills. That’s why it’s essential for all car owners who use their vehicles often to recognize signs of a malfunctioning engine and know how to address them properly.

Engine Light

When you see the illuminated check engine light, it indicates something’s wrong with your car. It could be anything from wiring malfunctions to broken spark plugs and more. Because of this, it’s essential to take prompt action by getting your vehicle inspected as soon as possible.

Mechanics can use OBD II scanners for an accurate diagnosis. They’ll read any sensors attached to the computer system, which will help pinpoint what component went wrong so you can get back on the road in no time.


If you notice your engine consistently overheating, it’s time to take action. Operating with an excessively heated engine can result in a host of issues, like warping cylinders and leaking coolant – both of which will cause white exhaust smoke. To avoid this, have your engine checked before further damage occurs.

Decrease in Fuel Efficiency

A decrease in fuel efficiency can be a sign of an engine malfunction. It occurs due to dirty air filters, which restrict the amount of oxygen fed to the engine. As a result, gas consumption will increase for each mile; this will not only lead to higher costs at the pump but also cause unnecessary noise and exhaust fumes.

Power Loss

Suppose you ever experience a sudden lack of power while driving your gas-powered car. In that case, it’s likely due to an interruption in the four individual strokes of the internal combustion engine that convert gasoline into energy. Each stroke is essential for moving forward, and if one fails at any point during the burning cycle, this will cause a disruption.

A Stalling Engine

If your car’s motor suddenly stalls while idling, it indicates there could be something wrong with the fuel system. It might be a malfunctioning spark plug, dirt accumulation in the filter, or any other component causing this issue. If these scenarios occur on and off, you should bring your vehicle to a reliable mechanic for immediate examination.

Having a Rough Idle

If your car vibrates while stopped at the traffic light, although you haven’t yet stepped on the gas pedal, it’s likely rough idle. It happens when an engine doesn’t function properly and uniformly. Ignoring this issue can result in serious damage to both its performance and safety down the line.

Too Much Noises and Vibrations

If you hear your engine making any of these irritating sounds – backfiring, hissing, popping, or knocking – something may be wrong with the combustion cycle. Furthermore, if you notice a lot of shaking coming from the motor, there could be an issue with one of its spark plugs. Suppose this needs to be taken care of right away. In that case, it may cause extra damage to other components inside the engine, so replacing them immediately should be a top priority for anyone dealing with such issues.

The key to preventing these problems is keeping your car running in top condition and serviced regularly. With the correct maintenance, you can avoid any minor engine issues before they become more serious.
