Pretty sure idle is set with the screw in the AAC. DO NOT use the throttle-stop screw (there's a reason it has a dollop of epoxy locking it in place).

hunt around for it, it will be on the iacv unit and its a flat head screw

it think someone lost ur flat head screw cos theyre usually flat heads i know mine is!

ps, ur throttle cable looks really tight lol, might wanna loosen it a bit if it is!

[xALmoN]

my throttle cable looks like that too.. so its in to lower revs and out to raise revs?

26dett its next to the throttle body iirc

no not at all

loosening the throttle cable nuts will only adjust the tension on the cable, if your cable is tight then it may alter your revs when taking your foot off the pedal because the throttle plate may not close fully instantly.

its always good to have a little bit of slack in the cable

also be careful when tightening the cable nuts above the manifold, the thread is only alloy or plastic or something, so tighten the nuts up hand tight, then just turn a tiny bit extra with a spanner.

On an RB26 it is under the inlet manifold in line with number 3 cylinder or thereabouts. There is a screw in the front of it. Clockwise to lower the idle speed, anticlockwise to raise it. If you car is hunting at idle then adjust the thing clockwise.

is that your engine bay? its brilliantly clean, thanks, i'll go hunt for it now, just want to know where the screw is, i currently idle around 850,

also I found by having a slight bit of slack in the cable my car isn't as jerky when you tap the gas the slightest bit.

yea, its common sense really, to have slack in the cable
