Subaru Forester stalling issue at stop lights despite battery replacement on Subaru Forester

Some Subaru Forester owners report experiencing stalling issues at stop lights, even after a battery replacement. This common problem may be linked to a drop in idle speed or the illumination of the check engine light following the battery change. Additionally, a dirty throttle body can lead to stalling without triggering any warning lights, necessitating a thorough inspection of this component. In some instances, owners have noted that their engine hesitates or stalls after stopping and attempting to restart, creating hazardous conditions in traffic. The auto stop/start feature may also contribute to these stalling incidents, as the engine may fail to restart properly when the accelerator is pressed. Some owners find that replacing the battery with one that has a higher Cold Cranking Amps (CCA) rating can help alleviate the stalling issue, even if the original battery appears adequate. To effectively diagnose and resolve the stalling problem, it is advisable to test the battery and charging system, inspect ground points, check fuel pressure, and verify the ignition switch's functionality.
