PAS sensor shouldn't make any difference on the move - it's only really there to tell the ECU to raise the idle speed a smidgen to compensate for the additional load. Can't see how the ICV would affect the steering either providing that the engine is turning quick enough for the pump to generate sufficient pressure.
Indeed, providing that the engine (and thus PAS pump) is spinning at a decent speed, you could have the ignition off and be rolling along with the car in gear and the clutch up and the PAS would still work just fine since it's a fully hydraulic system on a 306.
I've had similar symptoms before where the assistance would sort of cyclicly come and go when cornering under load but be fine when stationary or at low speeds, and swapping the rack fixed that - I assume that the PAS valving inside the rack was sticking or something like that.
Knackered steering lower columns can cause heavy/notchy/binding steering too, but that should happen when stationary too.
