1 Answers
Here are the specific reasons for abnormal noise when accelerating the car: 1. Exhaust system failure: Noise caused by exhaust gasket leakage or exhaust pipe perforation. 2. Intake system failure: Air leakage or poor sealing in the intake manifold or throttle body. 3. Engine chassis-related issues: Internal engine noise or loose surrounding accessories, or abnormal noise/resonance from chassis components due to looseness or interference. 4. Transmission internal failure: Abnormal noise during driving caused by insufficient lubrication or abnormal wear.
