Defect
The engine ECU control program has an incorrectly configured upper learning limit for correcting idle airflow. When carbon deposits accumulate on the throttle valve, the program may fail to compensate adequately, resulting in insufficient airflow at idle. As a result, the engine may stall at or near idle speed.
Corrective action
On all vehicles, reprogram the engine ECU with the corrected/updated software.
