Vacuum drop when AC switch on
is this normal?
While trying dignose a vaccum leak, I notice that vaccum will drop and fluctuate around 10 - 12 and A/F ratio leans to between 16 to 18:1 when A/C is on.
Please help.

The a/c on does effect the vacuum system. It is supposed to make the rpm's drop about 200 when switched on, but then it rises back to normal idle. Even when driving and coming to a traffic stop, it drops and comes back up. As for the air/fuel ratio, i really do not know if it effects it or not.

Andrew is your cv bypassed?
You could have a line loose and not know it. Have you removed your intake manifold to invistigate?
it's connected to your idle stablizer and could be the cause of your problem.
