How to Replace a Throttle Return Spring

How to Replace a Throttle Return Spring 1

On many vehicles, a mechanical throttle cable connects the accelerator pedal to the throttle. When the driver steps on the accelerator, the cable pulls the throttle open to allow more air into the engine. The throttle return spring pushes the throttle closed when the driver lets off the gas.

A weak or failed throttle return spring will prevent the throttle from easily returning to its resting position. This can result in engine racing and unintended acceleration.
