Why does my car lose power? In most cases, a loss of engine power will relate to a mechanical failure in your vehicle; however, the loss of power may also be due to an external factor such as high temperatures.
If your car is losing power while driving, there are a variety of different reasons which you can diagnose yourself. Here at OneHowTo we offer a number of possible answers to explain why your car loses power and give you some tips on how to fix the problem.
Your car can lose power because an injector has poor contact. If this is the cause of the problem you will notice that an exaggerated vibration will occur in the motor. We recommend that you maintain these parts well.
You can learn how to do this yourself by reading our article How to clean a fuel injector.
If your car is among those which have a turbo engine, something which is increasingly common, you may find it is this element that is responsible for the loss of power. It may be that a tube connector is damaged or simply dirty or poorly adjusted. The fault can also occur because the valve that regulates the turbo does not work properly.
If you put on the air conditioning your car will lose power. You will notice this especially if you do a road trip, or with a smaller vehicle used primarily for city driving. If you are overtaking whilst going uphill and have the air conditioning on, you will notice how the engine can feel like it is losing power. So be aware that the air conditioning will use of some of your engines available power factor when driving.
The cause of the car's power loss can be an overloaded cooling system. Under these conditions, generated by very high external temperatures, the fan has to act at peak performance. This takes away power to the rest of the engine equivalent to about 2CV.
For cars with an ECU (Electronic Control Unit), an error of this type can cause the car to lose power. In some cases the car may stop. This fault, which is not easy to solve, is due to the system which detects a mechanical error in the car without it actually existing, and gives the command to the engine to lose power or to stop in order to avoid an accident. Normally, after half an hour you can reuse your car normally, but you should go to a professional to repair the electronics.
If your car loses power when you accelerate or accelerates more slowly than usual, it could be that your catalytic converter may be blocking gases and thus not allowing your car to rev like it should. Visit a mechanic if this is the case. To check if your car is losing power because of the catalytic converter, you'll only need to pay attention for a rattle sound when you tap the catalytic converter lightly with a hammer or similar.
Another reason why your car loses power when you accelerate or doesn't do so when you press the acceleration pedal is because your fuel filter is bad.
