R33 Not Idling Smooth Help :(

[Alex_r33s2gts25t]

Hi guys, im new to the forum, this place has an amazing collection of information which i think is awesome.

I recently bought an auto 96 model series 2 R33 GTS25T and when its idling the revs sit around the 5-600 mark (seems to be low???) except when i first start it and the engine is cold itll idle just above 1000.

At the low revs the engine will shudder every now and then... does anyone know how i can fix this? (i am a n00b when it comes to cars i always get the mechanic to do everythin lol so dont skip on details thinkin i know .. thanx for ur help Guys

im not really sure but i think that 600 or thereabouts is the reccommended rpm for the r33's. i tried to leave it at that when i cleaned my AAC valve (dw its in the below link) but my ca also didnt like it. mines now in the 800 zone.

it goes up above 1000 because the engine is warming itself up. once it reaches temp it'll drop back down.

Just for a reference. When warm my R33 (manual) idles at around 700rpm I think. When cold its about 1100-1200rpm.
