Chevrolet Astro Throttle Cable offers the simple yet effective benefit of establishing a reliable link between the gas pedal and the throttle plate, instantly turning the driver's foot movement into engine air flow. Comprising flexible braided steel, this Throttle Cable starts at the pedal and runs straight through the firewall to the throttle body, where it pulls open a shaft on which a butterfly valve is mounted, letting more air in as the Powertrain Control Module lengthens the injector pulse for balanced fuel. Prior to the widespread adoption of the throttle body injection applied on the Astro, the Throttle Cable configuration was retained in order to work with existing air cleaner and intake configurations while still enabling better cold starts, upgraded mileage, and better emissions compared to carburetors. A later update from Chevrolet added electronic throttle control. This replaces the traditional Throttle Cable with two sensors on the pedal and a motorized blade. This helps the traction and stability programs, cancels sticking linkage when the cutter gets trapped, and allows finer idle control via the idle air control port. This is due to there being no longer any Throttle Cable in this drive by wire system. The main difference is obvious, mechanical cable operation versus electronic precision, but many drivers like the feel and easy service of the original Chevrolet system that kept the Astro responsive for decades.
