How To Fix Reduced Engine Power

When you’re driving your car, you rely on the engine to get you where you need to go. You turn the key, and the engine starts. And with gasoline being such a large part of our economy, it’s important that your engine can work as it should—every time. But what if your engine power is reduced? What do you do then? In this blog post, we will explore the different causes of reduced engine power and how to fix it. We will also discuss some preventative measures that you can take to ensure that your engine always performs at its best.

What are the Causes of Reduced Engine Power?

There are many potential causes of reduced engine power, some benign and some more serious. Some common causes of reduced engine power can include:

-Poor air/fuel mixture – Air is essential for combustion, and too much air or not enough fuel can cause reduced engine power. In a carbureted engine, incorrect air/fuel ratios will also cause reduced engine power.

-Incorrect spark timing – If the spark timing is off, the ignition system won’t produce an intense spark which can lead to reduced engine power. In diesel engines, incorrect spark timing can also cause knocking.

-Damaged or clogged exhaust systems – A damaged or clogged exhaust system will reduce the amount of oxygen available to the engine and can cause reduced engine power.

-Inadequate lubrication – Lack of lubrication will prevent the parts inside the engine from moving freely and can lead to reduced engine power.

Solutions to Fix Reduced Engine Power

There are a few things you can do to help restore engine power if it’s reduced.

Make sure the air filter is clean and free of debris. Dirty air filters will reduce engine power.
Check the oil level and change it if necessary. Low oil levels will also reduce engine power.
Clean the throttle body and injectors. Contaminants in the fuel system can reduce engine power.

How To Test If Your Vehicle’s Engine Is Low on Power

Testing for engine power is an important part of any car repair. If you notice a decrease in your vehicle’s power, there are a few things you can do to test and determine the cause.

One way to test engine power is by using a battery tester. This device plugs into your cigarette lighter and will indicate if your battery is providing enough power to start your car. You can also check engine codes with a scanner, which can give you more information about the issue that’s causing the reduced power.

If you’re not sure what might be causing the issue, it’s best to take your car in for inspection. A mechanic will be able to diagnose the problem and recommend a course of action.


If you are experiencing reduced engine power, there are a few things that you can do to try and get your car back up and running as quickly as possible. First, make sure that all of the fluids in your car are full and topped off. Second, check to see if there is any debris or dirt clogging up the air filter or fuel injectors. Finally, if you have a diagnostic tool like an OBD2 scanner available, it might be able to help identify where the issue is located.
