[SanLucille]

Ford Focus experiencing jerky and weak acceleration is due to persistent internal dirt and impurities. Below are detailed explanations of the causes and solutions for the Ford Focus's jerky and weak acceleration: Engine carbon buildup: Gasoline is not fully absorbed into the engine, leading to carbon deposits. Solution: Clean the engine and replace the engine oil. Throttle body or fuel injectors not cleaned for a long time, spark plugs not replaced for a long time: This can cause intake manifold failure or engine misfire, affecting fuel atomization and combustion, leading to a series of issues.
