5 Signs of a Failing Engine

Combustion engines are complex machines made up of over 200 main parts–thousands if you count every nut and bolt. Each is important to proper engine function. While quality ones are built to last, this means there are ample opportunities for any given part to fail and your car to break down.

The good news is that there are some typical indicators of engine problems. Once you know what they are, you can schedule auto repair.

Below are five engine problem signs to look out for. Keep reading to learn how to identify them and what they might mean for your car.

1. Engine Knock

As the name suggests, engine knock is a persistent knocking sound when your engine is running. It often results from pockets of air and fuel burning unevenly or on their own (as opposed to being ignited by a spark plug when you start your car).

This could be due to faulty spark plugs or carbon deposits. It could also be a sign of more serious issues with your engine. Whatever the cause, it is important to schedule a maintenance check.

2. Decreased Fuel Efficiency

This issue is more obscure but is still detectable. If you notice an abrupt drop off in gas mileage–such as having to refuel more frequently–it could be a sign of engine issues.

While there are many things that can impact fuel economy, an engine running properly will use about the same amount of fuel during any given driving duration. A sudden drop in gas mileage could be a sign of inefficiencies in the engine.

3. Vibrations

Vibrations while driving can result from issues with lots of different parts of your car. These include loose or warn-out components, or misalignment. They also can stem from engine problems.

You may be able to discern engine vibrations, as they will originate from the front of the vehicle. The most common cause is faulty spark plugs, but it could be a sign of more serious problems as well.

4. Stalling

Engine stalling is another common problem to look out for. This can arise from other issues, such as electronic failures, but stalling can also be a sign of engine issues.

These include clogged fuel injectors, fuel pump defects, and myriad issues associated with power loss. Regardless of the cause, a stalling engine is cause for auto repair.

5. Check Engine Light

This one might seem obvious, but it is often ignored. A check engine light means something is going on with your engine, be it a minor or major problem.

Most cars have a separate light that signifies regular auto maintenance is due. In short, if your check engine light comes on, you should get it to a repair shop quickly.
