Why does my car rev up when I have a vacuum leak?
If you have a vacuum leak, it will allow more air to enter the engine – allowing it to rev up. This is why you will, in many cases, experience a high engine idle RPM if you have a vacuum leak somewhere around the intake manifold.
Can a vacuum hose backfire on an engine?
Backfires are not good on engine components and if gone unresolved, can lead to catastrophic engine failure. A vacuum hose is a rather inexpensive component, but it’s very valuable in the overall operation of your car, truck, or SUV.
What to do if your vacuum hose is bad?
A vacuum hose is a rather inexpensive component, but it’s very valuable in the overall operation of your car, truck, or SUV. Take time to be proactive and recognize these symptoms. If you notice any of the above warning signs, take action and contact a mechanic ASAP to fix the bad or failing vacuum hoses.
What happens when you have a big vacuum leak?
If you have a big vacuum leak, you can often experience a rough, high or low idle RPM. This is because the throttle body is trying to get a stable idle by opening and closing the throttle. If you have a major vacuum leak, the throttle body will get problems trying to control it and it will result in strange idle symptoms 2. Rough/Slow Acceleration

Why does a vacuum leak cause rough idle?
Large vacuum leaks can also cause high or rough idle because the throttle body is controlling the idle RPM and when you have a vacuum leak, the engine will suck air from the leak and the throttle body will have problems controlling the idle properly.
Can a vacuum leak cause a check engine light?
Vacuum leaks do often result in a check engine light and stored trouble codes in the engine control unit. Because the air flow meter is reading one value, and the vacuum leak will cause the air/fuel mixture to get leaner, you do often get trouble codes about a lean mixture or misfire trouble codes.
