Hey guys,

heard this term thrown around a lot in regards to idle control. What is it? Where is it and do you think cleaning it will help my cold start idle up because at the moment the car struggles to idle up when cold, I have to give it a hand with the pedal....

sorry for a rather crappy thread but I did search first......

cheers!

cool i wanted to know about this aswell cause i had a dodgy idle regardless of cold or warm the engine would spike idle to 1500rpm.

it has gone away since i changed the sparkies, engine temp sensor and thermostat but i got told to check this out aswell.

can i ask another abbreviation question.

what is the AFM???

cause i got told to clean this thing aswell. i did a search but nothing came through i don't know if the search this has been disabled or something cause its been going on the last couple days.

hey guys,

finally got around to doing this........ I think.... Are you meant to take off the little brass cloured thing with the plug or the actual metal part with 4 bolts holding it and a gasket? I wasn't sure so decided to take off the brass part and in the process nearly lost the little spring!! It looked perfect so I blasted some CC down the hole where it goes into the metal thing.

seems a little better, do I need to take the other part off to do it properly? Will that gasket need to be replaced or will it be okay?

cheers!

The AAC can only control rpm within a limited rpm range, more like fine tuning.

Most of the additional air the engine needs during warm up is supplied by the air regulator.

It's mounted under the throttle body on the inlet runners.

It has a hose in from before TB and a hose out to the inlet manifold as well as an electric plug and it allows air to bypass the throttle body during warm up.

If it sticks open you get a fast idle but if it sticks closed it'll have a slow idle or stall when it's cold.

    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
