A/C making car idle low?

My ac was broken in my '03 civic and just fixed it but now i run the ac and the RPMS are below 1000 but when its off it idles just above 1000. the car also jerks at random when not shifting. is this normal?

My car does that too sometimes when I just start it. I know it's not my clutch because I have a Clutchmasters FX100 clutch. Acually it does that sometimes when the AC isn't on. But only when I drive it right after a cold start.

Two problems. 1. stock idle without load is 700+/-50rpms. 2. Using the a/c should usually raise idle by 100rpms when its on.

Exactly, you shouldn't be idling that hgih to start. And when you turn on the AC the computer should sence a load and increase the RPM about 100 RPM, which should still be below 1000RPMS.
