idle problem - 95 jdm wrx
 

hi there,

i have a 95 wrx which runs fine (pulls really strong and holds boost)

the problem i have is that if i rev it and let off or when i pull upto a junction.........the revs drop like it might stall (just for a second) and then idles fine.

it has a hks induction kit,blitz ss bov and blitz nur spec exhaust.......in case they might be a factor.

it passed its mot this morning and the emmissions were fine.........but its been stood for a few months (at least) as ive just imported it.........thought it might be the idle control valve sticking or maybe an air leak.

thought i would ask in case its a common prob.......thanks in advance.

bds.

anyone?

dont worry about it man, my freshly imported 98 sti type r does it aswell, running it on good fuel, m int condition, has full decat exhaust, hks ssqv and induction..have clean idle control valve and helped a small bit but still does it,just a scoob thing i think, id like to know does this happen to anybody with the original airbox still in place!?

Sounds like the idle air control valve needs cleaning to me. My 93 WRX used to go like that every 6 months or so. Its only a half hour job to take it off, clean it and replace.

thanks for the info :)
where exactly is the valve and do i need to be careful of anything when i take it off?
