Idle screw evo 3

[user5090]

checked my screw today it was very loose, i could lift it up with my screwdriver i had problem with idling when varm engine without ac on my idle was 1000-then to 1500 then back to 1000 then 1500 again and so on. with ac on it was 900 then to 1300 sometimes and so.

I turned the screw 2 laps to the right and my idle was directly 850rpm and it has been stable on this now for somedays. no more jumping with warm or cold engine.


but will the car goes worse if you manually adjust this screw? mine was very very loose i cant think it shouldnt be like that.
