Q: My car is powerless and noisy. What is wrong?

你好呀。From the description you have provided, drive about 5-10 km engine starts to make strange noise, could be so many possibilities. Checking the engine oil level would be highly recommended. The noise from the engine area needs to be isolated. It could be, an internal engine noise, ie; piston, connecting rod, tappet, timing chain, etc. It could be, an accessory component, ie; a/c compressor, alternator, idler pulley, tensioner pulley, power steering pump, etc.

此外，由于部分插头，缺乏功率和噪音可能是由于限制的排气催化转化器. The exhaust backing up in the engine can cause unusual engine noise.

因为有很多可能性，所以我建议您的车辆噪音和loss of power diagnosed并由认证的技术人员修理，例如来自Mymeneric的技术人员。万博体育入口
