CHECK ENGINE 灯亮了！

[zx188cn]

最近在旧车回收站换了台sunbird发动机（12万公里；$1000；保90天），感觉还行。昨天跑了500多公里高速也没问题。但就是CHECK ENGINE 灯隔几分钟就亮，亮几秒后自动熄灭。问回收站老板说没问题，但我总觉得不对劲。请教各位行家帮我分析一下。谢谢了！

Uusally that means your car's emission contral system got problem.
It might be oxygen sensor(s) got problem.
Parts are not cheap.
But the light may be gone after a while if you are lucky.
Add gas tank to full and 观察 several days.
Don't drive over 80km/hr if the CHECK ENGINE light is on.
