I did a home made smoke test and found that the end of one of my fittings was broken, I fixed than and my access port and obd2 are saying 17 . So if I had a real gage I would probably be in the good range now.

I have a 2009 outback xt. Specs. 100% stock. 111000 miles. 91 non eth. I have bad idle like its shaking, it don't matter if its in park n r or drive. I hooked up my obd2 and at idle I am getting a 13 vacuum, is that what could be causing the bad idle? I heard somewhere it should be 17+ on vacuum.
