请教各位一个问题

[WUMING]

今天在高速上开到100KM/H，突然觉得动力不够，速度降到80左右，加大油门依然没有作用，从后视镜中观察到尾气中有黑烟，下高速后停车半小时就没事了，我的车是六缸的，感觉像是有的缸不工作了似的，是不是SPARK或DISTRIBUTOR坏了？请高手指教！

then check Spark plug first. Remember, always check the possibility from the cheapest parts.
However, loose of one cylinder, could be various of reasons, but the appearance is more likely the higher vibration of the car. Cost of repair can range from $10 up to 4 digits. What year is your car? and Brand?

但我不太明白，Spark plug也有时好时坏的时候吗？

黑烟是combustion incomplete, 火花塞老了吧。
高速下发动机的温度和凉下来的温度对火花塞有作用的
