问：当我从加速器上脚下时，我的车很难保持跑步，尤其是在寒冷时开始时。

Hi Bryson. Thanks for contacting us tonight. On the fuel system of your Buick LeSabre, there is a component called the cold start injector or cold start valve. This helps to mix the air/fuel ratio to assist your vehicle start when it’s been sitting for a while. When this component fails, it can cause a lot of issues with the initial start. However, it’s also possible that the idle control valve or other fuel system component is damaged or simply clogged with excessive carbon deposits. It might be best to have a professional mechanic在您的位置检查车辆要正确诊断根问题，因此可以进行正确的维修。
