A vacuum advance that leaks or sticks cannot adjust timing as engine vacuum changes. Signs this part may need replacing include hesitation or sluggish response off idle, a drop in fuel economy, and a vacuum leak at the unit. If a failed vacuum advance is the cause, the VC-150 replaces it. Diagnose the ignition and vacuum system before you replace parts.
