For ** PETE ** : ) I looked at my controller valve, here's what I did... 850 1995

I'm sorry, I guess I neglected to state that our 850 wagon is a turbo. The two hoses (yellow and white) both go from the EGR controller to the IACV (idle air control valve). The only hose attached to the EGR valve goes from it all the way back to the turbo. So when I pulled off the hoses from the controller, they both had vacuum pulling into them. Does this make sense, or is something routed wrong?

I bought a vacuum tester today, and after I use it, I will report the results.
