R33 Gts25t Wiring Problem!

[MNTLRB]

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
