Anyone who's having problems with their pictures displaying, please post in this thread here: http://www.skylinesaustralia.com/forums/in...howtopic=166435

So we can try and figure out why it seems some people can see the pics fine, while others can't.

hey just cleaned my RB20DET AAC, fixed my high idle (1100rpm) brought back down to within specs, exellent DIY, would reccomend for all skylines

[Kwyjibo]

Did this and air regulator maintenance as in the other DIY thread. My idle is no longer 1100rpm!

[Crash.]

Did this one yesterday, there was alot of build up in the idle screw. Clean the lot with coton wool, then used the air gun to dry it all off...

Only problem i had was the hose at the bottom, what a pain that was to get off. Other then that it was all good

Nice write up

Well this is my first post but I have to say what an execellent thread. Thanks for effort you put into this. I have been having idling problems since I had some new parts on the car I will give this a try first chance I get. Thanks a bunch from the UK Insu, I just hope the R33 GTR is similar to yours.

ok stupid question i know but how far do i turn the idle screw in on the car (not the cpu) after i have cleaned it?

I have completed eevey step but not sure of where to set it to start the bottom steps (if u follow)

thanks

seems my car does not adjust its idle???

i tried screwing in/unscrewing the idle screw on the aac valve, nothing happens... sits at 900rpm

disconnect the TPS connector, does nothing.... still sits at 900rpm

what could be wrong?

Just another member saying this is an excellent guide! Did my car over the weekend and worked a charm, has never run so well. Mine was so filthy im not surprised that it made such a difference.

Cheers!

[jurule]

Did mine, too, pain in the ass to get the hoses off, but a few cuts and scratches later...steady idle at 7-800rpm. Was dirty as in there.

WOW this write up is sweeeeett!!!!!! iv had my r33 for around 10 months and im ready to burn the damm lemon over and over again!!! i have had idle problems from the the day my warranty ran out even total random cylinder miss fire iv spent roughly over $5,000 replacing part after part etc...etc.... but hardly no progress but i havnt tried this yet by chance the gods have forgiven me and this finally puts an end to my sorrows cheers keep you peoples posted

[Mobies]

All clean now was dirty as and runs like a dream i cant believe it all my sorrows are gone its a must all skyline owners duty to clean it cheers bro thanks a million

[driftmeister]

Just changed mine to a 2nd hand unit, the idling is so much better plus when braking the RPM doesn't dive down so low now. Runs like a dream now. Very good write-up.

Hi i tried doing this my rb25det was idling at 2300. I turned the screw as much as i could without forcing it and its still idling at 1600 does anyone know what this could be caused from? What should i do. Any help would be appreciated.

[Cubes]

Your problem is with the IAC valve. (cold start idle up)

Its located on top of the inlet manifold roughly below where the throttle body resides.

The spring can flick off and result in a constant high idle. OR it becomes gummed up and sticks a little.

I got it to idle at exactly 900 now thanks.
