How to Replace a Throttle Return Spring

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.

Chevrolet Monte Carlo V8-5.0L - Throttle Return Spring - San Antonio, Texas
Isai was able to arrive a little earlier than scheduled which was great. My car is an older car and it uses a carburetor not fuel injection. Finding a mechanic that knows how to work on a car with a carburetor can be a real challenge. I found Isai to be very knowledgeable and through. He answered all my many questions. He is very friendly. I certainly would use him in the future.
