What Causes Abnormal Noises in Front of the Engine?

[RemingtonRose]

Abnormal noises in front of the engine may be caused by carbon buildup in the engine throttle, exhaust system blockage, spark plug failure, muffler issues, cooling system malfunction, and other reasons. Carbon Buildup in Engine Throttle: The throttle position is closely related to the engine's power output. When there is excessive carbon buildup inside the engine, the vehicle's ignition energy decreases, and intake efficiency drops, ultimately leading to reduced engine power and symptoms such as shaking and sluggish acceleration. Spark Plug Failure: Spark plugs are also a common source of problems. Issues such as excessive spark plug gap or incorrect heat range can lead to poor engine combustion, resulting in weak acceleration when climbing hills. Insufficient tire pressure can also cause poor hill-climbing performance. It is recommended to check the tire pressure. Malfunctions in so many components can potentially lead to weak vehicle acceleration.
