my R32 GTR is idling high approx 2000revs on cold start its about 1600 then as it warms the revs climb

now the AAC valve has been changed and the new unit tested and ok

the air regulator has been changed and is fine also

it has been checked for air leaks and none found

hooked up to diagnosis computer thingy and no sensors showing any faults

has anyone got any ideas what might be wrong cause im out

Also i have just changed my gearbox and all oils replaced (gearbox, front and rear diff, and transfer box and attesa resevior (attesa system bled to specs of HPI mag article))

and now both my HICAS and 4WD lights are on (constantly at idle and itermittenly whilst driving) any ideas on this too?

Thanks people

dont know if this will help but on my s13 my idle was staying high, I coudlnt find any air leaks and I replaced the aac + air reg, but it did not fix the problem

In the end I found out that my TPS idle switch was not activating.

maybe have a quick look at that. There should be continuity between 2 of the pins on the plug, and when you open the throttle it should go open circuit..

mine was not showing continuity, so I looseded the screws and adjusted it and my car now idles normally.

      My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.

      I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.

      I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended

      I definitely agree with you there - I never click on content for cars I would never ever be able to get or compete with/against/be seen next to. Seeing a MX5 compete with a FD RX7 will make people upset though, for sure. Even in 2.5L Turbo form which is pretty grass roots. (or at least as grass roots as classic cars can be) Yes we're all classic car owners now.
