Didn't read it that way but if there is 18" at the valve doubt it would run at all. He said it was blocked may be the gasket underneath is burned through.Vacuum is at 18 hg to the EGR or idle vacuumn of the engine is 18 hg? Maybe I missed this
Is a scan tool available? What is the coolant temp and did you check the connector for corrosion or pin push back?
