4 Signs Your Car Has a Vacuum Leak

Your car has a lot of moving parts and all of them work together to keep your car safely on the road. Of course over time, some parts could break or begin to fail, which could lead to serious hazards and repairs. Therefore, it is important to know the signs of an issue. One common auto issue is a vacuum leak. A vacuum leak means air is not getting through to the throttle and engine and could result in a loss of power to your engine. With this type of leak, it is important for a certified mechanic to fix the issue as soon as possible.
