Why is your car revving too high?

The revolutions or RPM of the car is a parameter which affects the performance of your car, which is closely related to capacity and torque. In simple terms, RPM is the number of revolutions of the vehicle’s engine in 1 minute.

RPM stands for Rotation per minute, displayed on the rev counter on the instrument panel in the cockpit.

RPM is an important parameter that lets you know:

– Deciding when to change gear in a car with a manual transmission.
– Make the car maximize fuel by changing gear at the right time.
– Determine if the engine and transmission are working properly.
– Find the proper driving method to prolong the life of the motor.

Reasons why the car revs are too high?

If you are driving down the street and notice that RPM jumps when accelerating, this makes your engine consume more fuel. It can even cause the engine to overheat. It is necessary to check to find the cause and treat it as soon as possible.

1.- Vacuum leak

A leaky vacuum allows air to enter, increasing the amount of air in the combustion chamber of the engine cylinder.

At this time, the ECU receives the signal and adjusts the amount of fuel accordingly, which is the cause of the error that causes the RPM to increase.

2.- Clogged fuel injector

When the injectors are clogged with dirt and impurities, it will cause acceleration problems. Because the damaged injector is unable to deliver the exact amount of fuel to your engine, it can cause surges and stalls and causes RPMs to rise and fall, especially when accelerating.

3.- Dirty air filters

Air filters are your vehicle’s first line of defense by preventing airborne contaminants from entering the engine compartment. Over time, the air filter easily becomes covered with dust and other substances and generally loses its ability to filter the air that enters the engine. For this reason, unstable airflow can enter your engine, causing RPMs to fluctuate and causing you to have trouble starting or accelerating.

4.- Problems with time

Timing is more important on your engine because the timing of fuel injection and valve opening will determine the power of the engine. If the valve is out of date, it will affect the performance and fuel consumption of your car. This can cause the RPM to go up and down when accelerating

5.- Idle control valve malfunction

The idle valve is a component commonly installed on fuel injected vehicles with the function of controlling the rotational speed of the engine. If the valve fails or any malfunction occurs, the charging speed will be unstable, abnormally high or low, and will decrease or increase continuously. This is why the RPM jumps erratically.
