Idle Problem

[RellikZephyr]

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.
