The internal combustion engine naturally produces a vacuum while it is running, and engineers have learned to use this vacuum to control a number of other components in a vehicle. Because this vacuum cleaner controls so many different parts of a car, a vacuum leak can cause a variety of system failures and produce numerous symptoms.

Rough Engine Idling – Engine Vacuum Leak

The classic sign of a car with an engine vacuum leak is an idle engine. A vacuum leak causes a normal vacuum interruption that is created with a running engine. A vacuum leak alters an engine’s vacuum pressure, resulting in uneven engine idling.

Engine Hesitation: Vacuum Leak Symptoms

Along with a rough idle engine, engine hesitation during acceleration is one of the most common symptoms of an engine vacuum leak. During acceleration, the vacuum pressure of the leaking engine is more pronounced, presenting as an engine wobbling or hesitating.

Inaccurate Transmission Shift: Vacuum Leaks Symptoms

Engine vacuum provides a large portion of the transmission’s operating power, power that helps to properly shift gears in the transmission. An engine vacuum leak can cause weak or inaccurate transmission shift points.

Poor acceleration: vacuum faults in an engine

A vehicle with a vacuum leak will often have poor acceleration and reduced engine power. This is due to the exhaust of the engine vacuum which reduces the overall force and pressure produced by the engine during combustion.

Difficult starting of the vehicle: air leak in the intake manifold

Depending on the size and location of a vehicle’s vacuum leak, difficult vehicle starting is often a symptom of a vacuum leak. By reducing the optimal pressure and vacuum within a running engine, a vacuum leak can inhibit the action and operation of a car’s carburetor and / or fuel injection system, directly affecting vehicle starting.
