I have a car, Nissan maximum 97. Recently, I changed 6 spark plugs ( there is a oil leaking in one of them). After changing, my engine light is on. Could someone please tell me why and how to solve the problem?<O:p></O:p>

find a odb II reader, read the code, then you will know what is the problem.

的原因可能有多种，严重或非严重的硬件原因或软件原因。简单的可能是传感器，严重的可能是控制软件。不该轻视，最可靠的办法是送去车行检查。

是自己换的火花塞吧？六个火花塞应该是六个汽缸，不知道更换的时候有没有移动什么或者拔了什么接头之类的，再仔细看看电线的连接，安装得妥当不妥当。如还是没发现就要找专业人士查code了。
