Q: Intermittent misfire that sets a random misfire code and three injector circuit failure codes.

asked bySeptember 29, 2016

间歇性失火主要是在负载下加速和热加速时。我已经跑了几瓶heet和几瓶海雀,穿过汽油。我已经清洁了节气门主体,IAT传感器和IAC阀。我已更换火花塞,线圈包,油门位置传感器,凸轮轴位置传感器和曲轴位置传感器。我对喷油器进行了抵抗测试(每个注射器)。但是,它仍然间歇性地错过了。

Hello.

间歇性和随机失火可能是由许多事情引起的。如果所有这些组件都要检查,则可能有一个燃料喷油器脏或堵塞,并且无法正确输送燃料。可能需要清洁或更换其中一个喷油器。燃油压力问题,真空泄漏或发动机管理系统问题也可能引起随机失火。您的机电技术人员可以来您的家或办公室万博体育入口诊断您的失火问题replace the fuel injector如有必要。

问候,
