What are the symptoms of an intake manifold leak?

[HaydenMarie]

When there is a leak in the intake manifold, the most direct consequence is an incorrect air-fuel mixture, which may trigger the engine exhaust warning light. In severe cases, the engine may produce abnormal noises, experience elevated idle speed, difficulty starting, lack of power during acceleration, or even stall while driving. Below is some relevant information: 1. The intake manifold is a component of the engine's air intake system, responsible for distributing air to each cylinder. The inner walls of the intake manifold are smooth to reduce resistance. If a leak occurs in the intake manifold, it can disrupt normal engine operation and requires attention. 2. If a leak is detected in the intake manifold, it should be replaced with a new one. Intake manifolds in engines are typically made of plastic and may crack over time. During routine car maintenance, it is advisable to inspect the intake system for any abnormalities.
