问：P0301
I have replaced every ignition coil and spark plug costing me about 280 dollars and still have problems with my cylinder 1 I checked to make sure all parts are working. I suspect it's the wire that you plug into the ignition coil as it doesn't affect the car if plugged or not but the other 3 do.

诊断故障代码P0301意味着第一号缸失火，但其原因可能非常多样化。喷油器可能只是死亡，或者由于燃烧的阀或泄漏的头部垫圈而几乎没有气缸压缩。测试线圈的电源，好像必须诊断出电源电路（包括PCM）的线圈以查找故障。如果线圈有动力，我会检查燃料喷油器是否在功能并检查压缩。如果您希望通过经过认证的机械师执行这些步骤，请派遣万博体育入口到您的位置，请要求诊断障碍响应认证的机械师将为您诊断并解决此问题。如果您有其他疑问或疑虑，请随时重新接触万博体育入口。
