Idle surges when a/c is on?
So I have been having idle problems lately with my 90 22re and just when I think I have it under control, I hit the ac button and the idle starts jumping between 12-1600 rpms! what gives!

in my 90 mazda miata (yea i have a miata) The idle goes up when i put the AC on. Its normal in my car, because the motor works harder to run the AC...hence the lower gas mileage from using AC

I didn't know that's what that thing was. I'll try that later today.
I shouldn't have any vacuum problems I had some lines replaced that were bad. Should all be working now.

Not uncommon for the fitting to be clogged where it enters the intake plenum. Easy test is to bypass the VSV and just connect the line from the intake to the fitting on the idle up valve. If idle goes up, then the line and fitting are open. Then see if the VSV is open inside, they can get clogged as well.
