Ok, went to Shucks, popped the hood and checked the vacuum line (running from the PCV on the */C to the brake booster) while the car was running. I did not feel any leaks.
Shut the car off, pulled the vacuum line off the brake booster check valve, started the car back up (it sounded like I had put an aftermarket cam in the car
) grabbed the vacuum line coming from the top of the */C and put my thumb over it. It'* not lacking any vacuum
and the car resumed normal purring.
I think the check valve and the rubber grommet are on their way out. Shucks did not have it, so off to the dealer I went because I need brakes. The GM part #, if anyone is curious, is 18029764 for $22.80. It is both the check valve and the rubber grommet.
I also ordered a coolant recovery tank, pt # 25636828 for $19.09. How is the coolant tank cheaper than the check valve
The one I have right now has a crack where the plastic was joined together and I am getting debris in the tank.
Thanks for all the replies!
