Q: Misfire on cylinder #1

onNovember 30, 2016

Hi there. I just got a Dodge Ram 1500 5.7 hemi from 2011, like a week ago. A few days ago I went to snoqualmie and when I wanted to get on freeway I pushed it a lil hard and the check engine light came on and flashing and then went off, felt that I lost some power too. On the way home same problem happened when I was trying to passed another vehicle. Since then when I try to push it harder, I mean the rpm goes over 4000, the check engine light comes on and flashing and runs rough and car feels like it has no power. The code that appeared on the scaner was p0301 which said a misfire on cylinder #1. I changed the spurs plugs and put a new coil from oreily and still misfire on cylinder #1. Any suggestions about this issue? Thank you

你好。闪烁的检查发动机灯是计算机检测到对车辆排放系统组件有害的条件。继续使用闪烁的检查引擎灯驾驶会导致排放系统的损坏,特别是车辆的催化转换器。在某些情况下,计算机甚至会降低功率输出以保护发动机和组件,这可能是您在灯光亮起的情况下闪烁时明显损失功率和性能的原因好兆头表明该发动机仅在重载下遇到问题,并且可能与气缸1失火有关。圆柱体特定的失火可能是由各种问题引起的。如果您已经具有气缸1线圈和火花塞,那么我要看的下一件事就是喷油器。如果气缸1喷射器故障或堵塞,则可能无法提供正确量的燃料,从而导致失火。如果真空软管或进气垫圈允许无矩的空气进入发动机,则真空泄漏也会导致失火。我建议您拥有一名专业技术人员,例如您的机械技术人员,来到您的位置万博体育入口诊断圆柱体特定失火的原因
