Why is the Camry's acceleration noise particularly loud?
2 Answers
The loud noise from the Camry is likely due to issues with the fuel line, ignition wires, etc. Specific reasons are as follows: 1. Fuel line: This could be caused by fuel line blockage, poor flow, rail pressure issues, or abnormal operation of the electric fuel pump. It may also result from a clogged fuel filter due to various reasons, obstructed fuel delivery, or injector abnormalities such as quality defects, blockages caused by foreign objects, poor sealing, aging O-rings, and other malfunctions. 2. Air intake or idle control: Issues may include a dirty or leaking stepper motor or throttle valve body. Abnormal readings from sensors monitoring atmospheric pressure, temperature, or throttle position could also be the cause. 3. Aging or cracked ignition wires: This can lead to electrical leakage or insufficient ignition strength. Poor contact due to installation problems is another possibility. Recommendation: Replace with original ignition wires.
After driving a Camry for so many years, I've found that loud acceleration noise is often caused by insufficient engine maintenance. Like me being busy with work, I often neglect regular check-ups, resulting in carbon buildup in the cylinders, making the piston movement particularly noisy, especially during low RPM acceleration with a noticeable hum. Also, aging spark plugs that don't ignite timely can increase engine noise. I remember last time after cleaning the carbon deposits at the 4S shop, the noise reduced significantly. I recommend doing a deep clean every 20,000 kilometers and using higher-quality engine oil to reduce friction, so it doesn't sound like a noisy tractor. Additionally, check if the intake system is clogged, affecting air mixture. Paying attention to these small details can make the car run smoothly and quietly.
