Q: My car is jerking back and forth at high speeds

The first thing that needs to be done is to connect a scanner to the car and retrieve the code. This information will lead a technician down a diagnostic path. There is an important distinction that needs to be made here. Does your car "jerk back and forth" while accelerating or at a cruise when the throttle and speed are held steady? These are different circumstances in regards to what could be wrong.

Surging at a cruise is usually a sign of a lean running condition caused by fuel system components. This could be the马夫， 一个injector，，，，燃油压力调节器， 或者燃油泵。加速同时加速和抽搐通常是对点火组件的作用。如果存在真空泄漏或燃油泵无法提供足够的燃料，则可以获得类似的症状。问题可能是其中几个的混合物。

As for why it doesn’t happen after twenty miles, this could be because a motor needs more fuel to run when it is cold. If the fuel system is performing as it should, this could easily be the cause. Several components have warm up cycles that may not be working correctly. If they warm up to slowly, numerous drivability issues can arise.

我建议让你检查引擎灯光诊断由合格的技术人员（例如来自Mymeneric的技术人员）来帮助您解决这个问题。万博体育入口
