v2 sti nearly stalling when pulling up to stop

[Stacov]

hey guys/gals

Got a v2 sti just pod/blow off valve as mods. When i goto stop the revs drop pretty much 0 and nearly stalls but goes back to normal idle. Only seems to do it once the motor is upto temp apart from that its running sweet.

I cant see any broken pipes or hear any air leaks

If anyone had similar problem or got any ideas just chuck them out there

cheers

remove that fancy blow off valve (vent to atmo i bet) and try a factory one. see how you go.

if that cures it, either stick with it

or readjust your aftermarket bov. or replace if its worn.

Still did it with the factory blow off valve. I took off the pod and put on the factory box took it for a big drive and it didnt do it once ?

So dunno whats going on there might pay to leave the factory cold air box on. Could of been a leak somewhere will see how it goes.

Check your oil levels. Mine has been doing it too recently and my oil pressure gauge went right down as well. I checked and oil level was quite low. That may be it.

+ 1 for leaving factory airbox in

my sti v3 does that, basically slow down and it drops the revs right down when idling after it has warmed up. Almost zero but never stalls itself.... yet....

have no mods apart from a upgraded panel filter, but even before that it still did it...

might be a leak somewhere but other wise maybe its just normal?

Or you could clean your idle speed controller....

+1 for that, mine was "hunting" at idle really bad, tried changing back to factory airbox/bov etc nothing worked, then went to repco and got a can of special cleaning stuff, sorry forgot what it was called, and cleaned inside the idle speed controller and shes good as new......

Having this problem my self on my v3 sti, stalled a couple of times after a lot of boosting and coming to a stop. have a 50/50 blow off valve and standard air box and it still does it, should try plumming blow off valve fully back but haven't yet.

haven't tried cleaning idle sensor yet, shouldn't be any leaks as i just got engine fully rebuilt and it did this before i got the engine rebuilt aswell.

somebody said that it my be also to do with boost solenoid or getting too much air in fuel line when i boost then this causes is it to stall when i boost alot?

any thoughts on that? cheers.

just went for a good boost on full plumb back, improvement but idle is still dodgy.
