1. A method for operating a vehicle, comprising:
shutting down an engine via a controller in response to an engine shutdown request;
at least partially closing a driveline disconnect clutch and transferring torque from an integrated starter/generator to the engine after the engine shutdown request and before engine speed reaches zero following the engine shutdown request; and
delaying an opening of an engine throttle while a speed of the engine is less than a threshold engine speed as the engine is being rotated via the integrated starter/generator.
