Message I'm trying to figure out why I'm getting zero psi on a boost leak test with the boost leak tester with no signs/sounds of any leak. All I hear is air going through the intake tract. Is it possible the EGR valve is stuck open and letting air flow through? Wouldn't the throttle bodies prevent at least most of the air from getting into the plenum, enough to give me some sort of psi reading?
