Hey all Why does my idle move when im turning my steering wheel from side to side?????? The car idles normally but when i start to move the steering wheel the idle starts to move. what the hell is going on???

One last thing. My dog today has ruined my weekend. I woke up today and my dog has eaten the wires under the car at the rear for the 4WS. I have taken it to the auto electrician they have wired it all up again BUT......... the 4WS doesnt work. F%#$ dog im going to kill him. Any ideas what the hell it could be. The auto electrician has now unplugged the 4WS and he is going to have a better look at what happening with the computer that operates the 4WS. pisses me off though cause i now have the flashing light HICAS contstantly on now. annoying really.

It's normal...with the engine idling turning the steering wheel causes increased pressure in th PS fluid system and puts load on the pump. That load is transferred to the engine, which causes the idle to drop. R32's have an extra pressure sensor in the front PS lines that tells the ECU to bump up idles in situations like this (a bit like the air conditioner fast idle switch). R33's might be different, however.

most cars these days have the idle up solenoid which tells the computer to raise engine revs to compensate the extra load from the p/s when pressures increase(movement side to side) As for u hicas, get a lock bar. Try going to a mechanic with a scan tool and they might be able to delete the hicas light, or take the fuse out(if it has one) for the light :(

    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
