Engine overheating: When a faulty ignition coil is ignored for long enough, it may overheat, which can cause serious damage to the rest of the engine.
----------
Over longer miles, you do take a risk with unburned gas ending up in the catalytic converter and poisoning the catalyst, ultimately closing the pores in it. However, small miles driven may not matter.
请教：像我这种车况 （需更换火塞），能谨慎再开一段时间吗 （一个月）?
如继续再开，会不会造成更严重的问题？比如烧坏发动机？
现在天气太热，如有可能，想等九月天凉些再换。
谢谢！

1. 出车库 ASAP；
2. run and speed up the car ASAP;
3 avoid stopping As Much as I can;
4. stopp the car as quite & stable as I'm carrying 习近平！
5. terminate the Enginer ASAP.
Don't let the car has the chances to shake!
导致misfire的成因很多，并不仅仅只有火花塞或线圈这两个坏蛋会捣乱，确诊要拆卸后再排查，目测和扫码只是探诊。
短期少开或不开，低速非高速，就是费燃油毁三元催化器，反正坏事不少好事没有。
探诊不是确诊，N62的八缸自吸引擎动力不错，早期版本小毛病但修理费可不便宜。
