Throttle cable in your Subaru connects acceleration pedal and throttle body and carburetor. So when you press the acceleration pedal, the throttle cable transfers from pedal to throttle body or carburetor to open the throttle plate. Owing to the special environment, the throttle cable is easy to get stuck or loosen, further leading to throttle cable break or unresponsive. So if you find it is difficult to press acceleration pedal or the throttle does not work at all, there may be something wrong with throttle cable. One solution is adding some lubrication oil to it. Otherwise, you have to change a new throttle cable. Since you are already here, you can shop freely whatever you need. We promise that you offer all Subaru genuine OEM throttle cable with an affordable price.
