Steering issues

I have a r33 with the hicas lockout bars installed have had for quiet awhile but over last couple days have had issues with ps steering becoming hard (not like have no ps) then becoming soft again 

once Soft it won't go hard again ps pump is good and so is fluid 

anyone have a solution??

Start with the very basics.

No funny noises coming from the pump or steering?  If so investigate to see where it's coming from, or what it's associated with.

Any signs of power steering fluid leaks?  If so resolve them.

Power steering fluid reservoir at full mark?  If not fill it.

Power steering drive belt correctly tensioned?  If not fix it.

Power steering belt have any stray oil/fluid contamination so it can't drive the pump?  If so degrease it.

 

I don't think there's any likely relationship between the HICAS lockout and what you're describing, given it's only recently started happening.

Everything is good no leaks level is good
Belt is fine
It's very intermittent sometimes it's stiff to steer then it could be fine again

When this intermittent fault happens, get the bonnet up and a second set of eyes.  Look/listen what happens with the car stationary when the wheel is turned.  Also try to determine if the problem goes away if you stop the engine, ignition off/back on and restart.

Apart from having HICAS lock bar kit you haven't given much info to go with eg. what fault finding you have done, what other mods the car has etc.

Remarkably, others have experienced some problem or other in their HICAS.

Seems to be a linkage to other mods eg. aftermarket steering wheels.

Forum searching can help.
