Q: Misfire

asked byOctober 15, 2016

我的rpm仪表弹跳,没有在弹跳时弹跳。闲置或开车时,弹出噪音轻微。快速出色时弹出更多。在高速公路上还不错。压缩测试很好。我已经更换了插头,电线,盖,转子,燃油滤清器,空闲空气控制阀。仍然有问题。地图传感器或喷油器更有可能的是什么?

My car has 233000 miles.
My car has a manual transmission.

Hi there. From the description you have given, your vehicle has a combination of problems. The不稳定的转速计/RPM仪表可能有过错。点火模块的转速表信号可能是不稳定的,也可能是车辆驾驶性问题的原因。流行噪音让我担心。即使通过压缩测试已经过去。有可能的是,排气门无法正确打开(即;磨损的凸轮轴叶),将废气重新推入进气歧管。这发动机的弹出声听起来像爆米花机。我建议您通过Mymechanic认证的技术人员检查和诊断您的车辆问题。万博体育入口

From what you describe it is the front wheel bearings in the front hubs that need replaced. You should also check the tires for uneven wear and need for tire rotation or alignment issues causing uneven tire wear.
