Hi George

        Not sure I can explain- according to my Camaro shop manual. With eng
not running, apply vacuum to EGR valve. Start eng and observe vacuum. Valve
is good if valve moves to seated position(valve closed) and vacuum dropped
while starting engine. My valve works this way and earlier this year passed
smog test here in California.  Both pos/neg EGRs have an air bleed in
primary diahram to meter flow.  

Hope this is helpful Vance
