Vacuum Readings (Dipstick Smoke) 850 1994

Started the car pulled the dipstick and noticed a decent amount of smoke coming from the dipstick tube. I hooked up my vacuum meter and checked my pressures. At idle I got ~17 inches with the air conditioner running and a decent amount of smoke. With the air conditioner off I got ~19 inches at idle and almost no smoke. What pressure is normal at idle? Why is there smoke with the A/C running and none when the A/C is off? With the A/C on it seems to me there is too much smoke coming from the dipstick tube, enough to burn the top of the actual dipstick. Does anyone have any suggestions as to where to start looking? I checked as many elbows as I could and they all looked good. The cruise control doesn't work but I don't think it's due to a vacuum leak, unless someone here thinks that is probably the reason.

I appreciate any feedback!

Thanks in advance.

It's a 94 850 turbo with 205K miles.
