Idle speed up valve

anyone seen Denso idlespeedup valves will know what i am talking abt.

i noticed maybe due to driving in dirtywater or whatever reason, the idle speedup with a/c is at 800rpm where its supposed to be at 1k.

so i decided to chk it out, while trying to fix elki to increase idle speed..

i rotated the lower end of this and it came off from metal part. there is a cylinderhead with spring under and rubber shield (gasket) before rubber pipes from engine fix it,

i thought to replace it but efi engine valve has wider pipes, i found only thinner pipe valve fitting so i didnt replace.

anyway i cooled down the engine with little water so i could work and spray water behind engine so parts fallen off would fall on road under then i moved car back and found the small spring and cylinder on road.

then cleaned everything with wd40 and fixed it back, now i hear airleak when i rotate it , it is increasing idle 500 rpm only from 750 rpm to 800 rpm.

there has to be an adjustment screw on the device locate it and your problem is solved.my hint is it would be some where in the middle of thw diapharagm extruded externally with a chuck nut probably for locking .
