What Causes an Automatic Transmission Car to Stall at Idle While Waiting at a Red Light?

[Melissa]

Engine auto start-stop function automatically shuts off the engine when the vehicle comes to a temporary stop during driving (such as waiting at a red light). When it's time to move forward again, the system automatically restarts the engine. Below is relevant information: Disadvantages: The initial design purpose of auto start-stop technology was to save fuel. When the auto start-stop function is activated, the engine enters a "dormant" state during brief stops, the pulley stops rotating, and the system minimizes engine idling. Working Principle: The auto start-stop system is an onboard computer-controlled system that automatically starts and stops the engine. This system requires the installation of a starter with auto start-stop capability on the engine.
