What is often a result of an air intake leak?

An air intake leak primarily introduces unmetered air into the engine's intake manifold. This disruption in the air-fuel mixture can lead to poor acceleration performance. When the engine receives more air than the fuel system can compensate for, it creates a lean mixture, which can affect combustion efficiency. As a result, the engine may lack the power needed for smooth and responsive acceleration due to insufficient fuel in relation to the amount of air being drawn in.

In contrast, engine flooding typically occurs due to too much fuel in the mixture, which is not a typical outcome of an air intake leak. Improved fuel economy is not expected, as a lean mixture can cause the engine to run inefficiently, potentially leading to increased fuel consumption in certain conditions. Increased oil pressure is unrelated to air intake leaks, as it is influenced more by the engine's lubrication system and not by air intake issues.
