Buick LeSabre stalling and hard start issues possibly related to intake or head gasket on Buick LeSabre

Some Buick LeSabre owners report experiencing stalling and hard start issues that may be related to intake or head gasket problems. They note that an intake gasket leak can lead to coolant entering the engine, resulting in performance issues, while coolant leaks around the intake manifold seals can also cause similar symptoms without a blown head gasket. Additionally, some owners have encountered stalling due to a blown head gasket, which may present symptoms like overheating, white smoke from the exhaust, and coolant loss. Fuel system problems, such as faulty fuel pumps, filters, or injectors, are also common culprits for stalling. Air intake obstructions can further disrupt engine airflow, leading to stalling while driving. To diagnose these issues, owners are advised to check for error codes from the engine light, inspect fuel system components, and ensure spark plugs are functioning properly. Repairing intake gasket leaks or addressing head gasket concerns typically requires professional assistance, and replacing faulty components can help mitigate stalling problems.
