Those would be the fuel pressure, EGR, and EVAP (BVSV=Bimetal VSV/heat activated) VSVs. I'd say, out of the 3, the fuel pressure VSV is the most important.
You've gotta go hose-by-hose and make sure nothing is causing a vacuum leak. Check everything on your intake manifold. The rubber vacuum barb covers (on the passenger side part of the intake manifold) should be in good condition.
