Problem overview

Some Dodge Grand Caravan owners report experiencing intake manifold issues that can lead to serious problems, including fuel injector separation and gas leaks with a risk of fire. These intake manifold leaks can disrupt the engine's air-fuel ratio, resulting in noticeable performance issues. Additionally, a leak may cause the air-fuel mixture to become too rich or too lean, potentially damaging the engine and posing a fire hazard. Common signs of a failing intake manifold include engine misfires, which are often linked to disruptions in the air-fuel mixture entering the cylinders. Owners have also reported a decrease in power and acceleration, which could indicate underlying issues such as clogged fuel injectors, faulty ignition coils, or malfunctioning fuel pumps. It is crucial for owners to address these intake manifold issues promptly to prevent further damage and ensure the safety and performance of their vehicles.
