A distributor vacuum advance uses engine vacuum to advance ignition timing as operating conditions change. If the original unit leaks or sticks, it may need replacing. Signs include hesitation on light acceleration, sluggish part-throttle response, reduced fuel economy, or a vacuum leak that affects idle. These symptoms can have other causes, so diagnose the problem before replacing the unit.
