Hi guys

I have a R33 GTS25t s1 which i bought a while back. A previous owner decided it'd be a really good idea to unplug the throttle position sensor and cut the wire out of the loom....I know, stupid, I have been told that 'apparently' the RB goes harder if it doesn't know where the throttle is.... :) WTF do these people smoke?

Basically it runs perfect except sometimes at idle it revs up and down, up and down etc until either I tap the throttle slightly, or it stalls itself, really really annoying. Now my brother being an electrical engineer has the necesary skills to rewire this...except we cannot find on the loom where it goes! No sign of the old wire anywhere. Any help, advice, photos would be HUGELY appreciated, this is really f***ing me off!!

Thanks guys,

Rhys

Anybody have any ideas?

Right i have an idea for ya.....

I assume ur looking at the plug located up at the throttle housing, this plug has wires cut, mine too. i discovered that it was probably for the air mass meter newly located just after the air filter. the wires have been cut and a new loom added down near the air filter with an aftermarket mass meter.

I think ul find the throttle position sensor still located just behind the plug underneith the throttle housing with wires still attached.....

I had the problem with the rising and lowering revs, on mine this was caused by a build up of crap on the butterfly valve. just take off the ally pope to the throttle body and clean the valve and u should be running like new again........

Had a look at the throttle body, seemed fine, but gave it a clean anyway, its still not idling right tho.

Can't see any sort of aftermarket sensors on mine

What do you mean by a mass meter? Similar to air flow meter? Mine's still using standard air flow meter

      I mean it's a bit late to say "This won't have any tangible effect and it is not worth spending more than about three seconds on it, please just enjoy the car" But I said it anyway. Does the pod actually get any airflow in that position behind a bumper like that?

      Hey guys - apologies for digging this up. Has this website been shutdown or is the outage temporary?

      So, went shopping at Just Jap for things that might work for the intake  After some trial fitting there I ended up with a 3" x 45° silicone bend, a 3" x 300mm alloy straight, and a humped joiner, some minor trimming will be required to shorten some of the stuff, but nothing that is beyond my "ham fisted" skills The guy at Just Jap was most helpful as we had all sorts of joiners,  bends and stuff out trial fitting  Laying it out above the stuff in there it seems everything will fit nicely, and looking at it, it is probably the way I should have been looking at doing it from the beginning, probably..... In the end it is a front bar off job anyway to remove the original stuff behind the front bar that is taking up the required realestate needed, so maybe a Thursday or Friday job And because I'm a hopeless consumer, I grabbed some new steel wheel nuts, the current ones are a spline drive type with a "security" socket, that somehow someone keeps misplacing, the new ones are a basic black steel 17mm hex socket In other news: I just did my "final" tax return, I am now officially a old retired veteran pensioner, and I'm milking the system for all it's worth,  life is good

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
