The P0446 code indicates an issue with the Evaporative Emission Control System (EVAP), specifically related to the vent control circuit. While this code itself typically won't directly cause a car to stop idling, it can be a sign of an underlying issue that may affect engine performance. If there are additional problems with the fuel system or air intake, those could lead to rough idling or stalling. It's advisable to have the vehicle diagnosed by a professional to pinpoint the exact cause of the idling issue.
