1. A system comprising:
- 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.

Abstract
A system according to the principles of the present disclosure includes a stop-start module and a throttle control module. The stop-start module stops an engine when a driver depresses a brake pedal while an ignition system is on and the engine is idling. The throttle control module selectively opens a throttle valve when fuel injection in the engine is stopped while the ignition system is on based on engine speed and a manifold pressure within an intake manifold. The stop-start module starts the engine when the driver releases the brake pedal.
