  • a stop-start module that stops an engine when a driver depresses a brake pedal while an ignition system is on and the engine is idling, and that starts the engine when the driver releases the brake pedal; and

    a throttle control module that, based on engine speed when fuel injection in the engine is stopped and a manifold pressure within an intake manifold, selectively opens a throttle valve when fuel injection in the engine is stopped while the ignition system is on.
