You’ll Lose Engine Power if You Have a Vacuum Leak

You’d be surprised at how much havoc an engine vacuum leak can cause. Although rare, older automobiles can develop vacuum leaks over time. LP & Sons Auto Care can repair the vacuum leak by replacing the leaking vacuum hose. The vacuum that is produced in the combustion chamber is routed via the hoses throughout the engine to power various components. If you are experiencing any of the following signs of an engine vacuum leak, bring your vehicle to our shop right away.

Erratic or High Engine RPMs

As the vacuum pressure escapes from the leaking hose, it will increase the engine’s RPMs. If the pressure is blowing out of the hose in spurts, your vehicle’s tachometer needle will bounce up and down erratically. If the vacuum pressure is blowing out of the hose in a steady stream, you will notice that the engine’s RPMs are too high all the time.

Hissing or Suction Noises

Strange noises coming from the engine can also suggest that the engine has a vacuum leak. For example, the leaking hose may hiss or squeal as you drive your automobile. In some cases, the leaking hose will also make the same suction noise that you hear from your household vacuum hose.

Malfunctioning Components

As we mentioned in the introduction to this blog post, the vacuum pressure that is produced in the combustion chamber is used to power components. One such component is your vehicle’s power steering pump. If the hose that directs the vacuum pressure to the power steering pump is leaking, you may notice problems with your power steering such as a stiff steering wheel.

Noticeable Engine Power Loss

As the vacuum pressure escapes from the leaking hose, it fills the engine with air. Consequently, you will notice that your vehicle does not have the power that it normally has. This is particularly noticeable when you try to accelerate and the engine lags. Unfortunately, the only way to restore your vehicle’s engine power and acceleration is to replace the leaking vacuum hose.

Check Engine Warning Light

Finally, you may end up with an illuminated check engine light on the dashboard because of the vacuum leak. As the engine fills with air, system sensors will report malfunctions to the engine control unit. As a consequence, the unit will turn on the check engine light.
