Check for a vacuum leak in all vacuum lines.
Check all of your vacuum lines around and from both the AIRB and AIRD solenoids to their valves.
Make sure both AIRB and AIRD solenoids are working without leaks.
Make sure your air pump is working.
You may have to buy or rent a hand vacuum pump for the tests.
