I have a vacuum gauge and tested the system in that regard, per the fsm. I was able to get vacuum at 3000 rpm like the fsm states. BVSV at least was open at temp. This was before I even cleaned out the EGR, where the small stem that goes to the modulator was completely plugged. So it appears that stem does not need to be functioning in order for vacuum to get past the modulator and to the valve.
I think I am going to run it through today, with the baffle in place and the slightly functioning valve. Maybe I can squeak by. I am going to not warm the engine up, just drive the 3 miles to the testing place. The purpose of the warm up is a more complete fuel burn, and I do not have that problem in the least.
