Question about 1994 Toyota Corolla
When the aircon is on , timing is unstable, so while the engine is running it turns shaky ,or jerky but when the aircon is off, it goes back to normal , even if the RPM is appropriately set,
There is a valve on the intake manifold that increases the RPMs when the AC is on. Check for a vacuum leak at the hose going from it to the manifold, or the valve may be bad.

If your car is carburated engine, check the idle up control valve, once you turn on your AC, you will see this screw pushing the rod of your trottle you can easily adjust the screw by turning it counter clockwise to get the right RPM
