Is a vacuum leak serious?
Driving with a vacuum leak should not be done because it causes a loss of power to your engine. This can be unsafe while driving down the road, especially if the leak increases as you are driving.
What causes a vacuum leak to the intake manifold?
In a gasoline-powered engine, the downward motion of the pistons working against the throttle blade creates a vacuum in the intake manifold. A vacuum leak occurs when there's a leak somewhere, allowing unmetered air to enter the intake manifold.
Can a vacuum leak be fixed?
Part of that's due to the eventual breakdown of gaskets and hoses. Vacuum leaks come with that breakdown and are just one thing that will start popping up at some point. Dealing with the vacuum leak isn't usually the problem, they're fairly easy to fix even for novice wrenches.
Is it expensive to fix a vacuum leak?
Depending on the cause and location of the leak it can cost between $150 and $1,000 to repair a leak in your vacuum system.
Will a vacuum leak throw a code?
Vacuum leaks can often result in a check engine light on your dashboard, and you will often find a trouble code in the ECU memory telling you that the ECU recognized a lean mixture.
Will check engine light come on for vacuum leak?
Finally, because the vacuum system does not have a warning light of its own, your automobile's engine control unit will turn on the check engine light to alert you of the vacuum leak. One reason why this light is on is that there is too much air in the engine as we discussed above.
What a vacuum leak sounds like?
Hissing or Sucking Noises Usually, when the leak isn't too bad, you will hear hissing noises coming from the engine. This may also sound like whining sounds or whimpering sounds. For more severe vacuum leaks, the noise is sucking or suction, much like a vacuum cleaner.

What happens if your intake manifold is leaking?
A leaky intake manifold sucks outside air in, rather than dispersing air out. This can cause performance issues including poor fuel economy, decreased acceleration, and engine misfires. Coolant leaks can cause the engine to overheat, although they may not always be visible.
Can vacuum leaks cause misfires?
Vacuum leaks, especially those that are confined to one cylinder, will cause the engine to idle unevenly and possibly misfire. This is because the vacuum leak allows additional air to reach the affected cylinder, diluting its air/fuel mixture.
