Q: Hard shake and car died, accelerator not working

Shaking or vibrating may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faultyidle air control valve可能导致发动机空转降至正常空转rpm以下，这也可能导致电动机摇动或振动比正常情况更大。这会造成电力损失，在整个电动机中产生共鸣，并导致点火和燃料时机的其他问题。每当引起失火时，这会导致电动机失衡，从而导致电动机摇动或振动。可能引起这种摇动或振动的另一个问题是发动机安装损坏。发动机安装座通常是橡胶安装的牙套，可将发动机固定在汽车底盘上。当这些破裂或虚弱或故障时，这可能会导致发动机振动。由于这种类型的原因摇动或振动, I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
