What Causes the Abnormal Noise in Teana's Engine During Acceleration?

[McEmery]

Teana's engine abnormal noise during acceleration can be caused by exhaust pipe leakage, dirty throttle blockage, or engine misfire. Here are the detailed explanations: Exhaust Pipe Leakage: When there is a leak in the intake or exhaust pipe, the vehicle will produce a loud roaring noise as the exhaust rate increases during acceleration. Dirty Throttle Blockage: During acceleration, the engine load increases, requiring the throttle to open wider and more fuel to be supplied. If the throttle opening is not optimal due to dirt blockage, it can lead to poor air-fuel mixture ratio, resulting in noise during acceleration. Engine Misfire: Engine misfire mainly refers to one or more cylinders not working properly. Common symptoms include insufficient vehicle power, severe shaking of the exhaust pipe, and clear engine noises such as "popping" or thumping sounds. Solution: When abnormal engine noise occurs, it should be repaired promptly to prevent further damage. It is important to note that if the noise is coming from inside the engine, most drivers cannot fix it themselves and should take the vehicle to a professional repair shop.
