问:有一条嘎嘎声,它刚刚消失,但被催化转化器的光所取代。...我还能开车吗?

onJanuary 13, 2017

there was a rattle on my car for a few weeks.. but the local garage couldn't find anything wrong. The rattle got worse, then seems to have stopped but now my catalytic converter light has come on!

我的汽车有63000英里。
我的车有手动变速箱。

I can’t say with any assurance whether it’s OK to drive without hearing the rattle myself. It really could be anything and I’d need more information. But I’m going to guess that your catalytic converter is coming apart on the inside. That would explain your subsequent catalyst code. When the catalyst has been very hot, or maybe if you bottomed the exhaust on a speed bump, sometimes the ceramic substrate inside the catalytic converter will break up. And the pieces roll around inside the housing sounding like so many rocks in the exhaust. They can become wedged and stop rattling for periods of time, but will eventually start again. Sometimes the pieces can get wedged together and block the flow of exhaust to the point that the engine begins to run poorly. You need to have the ECU scanned for more codes, because if the catalyst did indeed break up at such a low mileage, there might be some other problem that caused the engine to run too rich and the exhaust to get too hot. I suggest you contact Your Mechanic about having a technician come to your home or office to连接扫描工具并告诉您什么困扰您的汽车。他们也可以听你的嘎嘎声并给您第一手评估是否可以安全开车
