Q: Car hard starts, rough idles , fan on all the time and stalls when accelerating.

你好。

The symptoms you are experiencing can be caused by many things. A few things I would look at are the fuel, ignition, and engine management systems.

如果这些系统中的任何一个组件都存在问题，那么它们可能会引起性能问题。如果有问题燃油泵,ignition coil, or空闲空气控制阀then the vehicle may experience all the symptoms you describe.

I would also take a close look at the temperature sensor, as in some vehicles it is responsible for powering on the fans, and can cause them to malfunction if it goes bad.
