I wish I had the problem of turning the A.C on it's 27 and cold where I am. Enjoy the weather.

Nothing to worry about; that's perfectly normal--especially when you turn on the AC, or heater.

i've been wondering the same thing. my vac is just shy of 20, when i turn the ac on it goes to 16 maybe, somewhere around there, the revs drop etc...i've been fixing my o2 and plugs alrite, hopfully i got everything figured out.

It was about 89 today here in Orlando and my AC has a damn leak in one of the lines. I really need to fix it!!!

my vacuum always sits at 14-16 when idling even if I turn on the ac or heat. don't get it, but the car seems to run fine, just a little rich, even at 9psi!!!
