If you notice your engine running very slowly, idling with hesitation, or stalling, you may have an engine vacuum leak. The engine computer compares data from several sensors to detect the problem and log a fault code. It will then send an alert to your car’s dashboard.

Stalling in hesitation:
Engine vacuum leaks can cause problems with engine performance, such as excessive idling and stalling. They also cause the engine to lose fuel, causing it to perform poorly. This can lead to other performance issues, such as stuttering or hesitation at high speeds.
The symptoms of an engine vacuum leak include high idle, stalling in hesitation, sputtering, or hiccuping while driving. These symptoms can be caused by a vacuum leak, as air spurts from a leaking vacuum hose hit the engine. An engine that stalls and hesitates can also be difficult to start.
Sporadic idling:
A sporadic idling is often a symptom of an engine vacuum leak. When a vacuum leak occurs, excess air in the engine reaches the combustion chamber, causing the engine to run poorly. This can lead to rough idling, sputtering, and acceleration loss. In severe cases, the engine may even stall.
To diagnose a vacuum leak, you must first determine what is causing the problem. You should check the vacuum hoses. These may be prone to wear and tear under high temperatures. Another possible cause could be a cracked or blown head gasket.
Idling with hesitation:
You probably have an engine vacuum leak if you experience idling with hesitation while idling your vehicle. When this happens, there are several different consequences. Not only will the engine start idling very slowly, but it will also lose power and stall. A vacuum leak can cause your vehicle to run lean and waste fuel.
Idling with hesitation is a sign of a vacuum leak:
A vacuum leak in your engine can cause a high idle or stalling. This means there needs to be more air to make the engine run smoothly. You can tell if your cars idle is too high or low by looking at your tachometer. You’ll see that the needle will increase and then drop again. The engine will also be difficult to accelerate.
