6 Reasons Why Your Car Engine Loses Power and the Solutions


During the course of car usage, wear and tear of the engine components can run your engine down. These are normal things that happen to a car’s engine and can rob you of horsepower, torque, and fuel mileage over time.


What are the actual causes of this lose in power you may ask. Here’s a complete breakdown of some of the reasons why your engine is not performing like it uses to anymore.

Air Filters

As time goes on,the air filter of every engine starts to collect dusts and debris. These substances blocks the airways and prevent the engine to take on enough air required for proper combustion of the fuel. This in turn reduces the total performance of the engine.


Replacing of the air filter every now and then is advised

The Throttle Cable

This applies to cars with mechanical cables. With time the cable wire might get loosen and at such you will not be able to open your throttle all the way. If you can open your throttle all the way,of course your engine won’t produce enough power.


Tighten your throttle cable if you notice its losen or replace it entirely

Exhaust Muffler Clogging

Over time,the exhaust system traps a lot of particles and as such the muffler gets clogged thereby restricting airflow through the exhaust system which leads to additional pumping loss and subsequent engine power loss.


Exhaust system should be randomly cleaned

Fuel Injector/fuel Pump

As a result of heat and also the use of poor fuel,the fuel injector/pump can get blocked from particles from the tank or from the combustion chamber and therefore won’t supply fuel efficiently to the engine.

This can lead to misfiring which in turn reduces the combustion rate of the engine and thus leading to loss of power



Regular servicing of the fuel injector/pump can solve this

Piston and Rings

The rubbing of the piston and rings on the wall of the cylinder leads to wearing of the piston over time. This leads to the less compression in the engine. This also causes decline in engine power.


Regular changing of the engine oil will help to reduce this by proper lubricating of the piston and rings

Spark Plugs

The spark plugs can get clogged over time from oil,fuel and carbon deposits. This can lead to misfiring and inconsistent sparks. Leading to inadequate engine performance.


Always change your spark plugs regularly.

These are the major things that can lead to your engine losing its power. Follow all the above mentioned advice to keep your engine in proper working condition .
