我的汽车大致闲逛而失踪。我不确定这可能是许多事情之一:火花塞,转子盖,塞子线或节气门主体可能需要清洁。

失火通常会导致粗糙的闲置,但是您必须找出它是一个圆柱体失火或随机失火,这是扫描工具是必不可少的。If you can trace the misfire to one cylinder its usually a coil pack or injector but if its a random cylinder misfire your looking at air/ fuel delivery, vacuum leaks, dirty mass airflow sensor, "lazy" 02 sensor that doesn’t respond fast enough, or a fuel pump thats on its way out. Have a mechanic like one from YourMechanic check for codes and look at the real time engine data while its running.
