Engine vacuum numbers?
I checked engine vacuum at different locations. Do these number sound right to you? All at idling, warm engine.
1. Brake booster: 23 mmHg
2. Vacuum manifold behind battery: This manifold has 5-6 vacuum tubings. I removed the cap of an unused port and checked vacuum. 15mmHg vac
3. Purge valve solenoid: The fuel vapor purge valve solenoid is vacuum operated. 1/8" (could be metric) tubing. 0 mm Hg vac
