redtop sr20det help please (SORTED)

so im having a problem with my sr, its seems to idle fine but when im coming to a stop when entering a roundabout it almost and sometimes cuts out, also when i rev it it almost cuts out
what ive done so far is

new plugs
new walbro fuel pump
new fuel filter
cleaned the afm (its a standard one)

there are no boost/air leaks anywhere
as i said i done the above but they might have nothing to do with it

i was thinking it was the idle control valve maybe? if it is could someone tell me how to remove it as i dont have a clue.

if someone could point me in the right direction as this is wrecking my head at this stage

heres a quick video of it running and me reving it

Thanks

Fit a STD dump valve.

Robbie

check that its not stuck open a bit or its not seating right.. it could be dumping air as its idling like robbie said.
if not you have to find your iacv take it out and clean it up also to make sure the springs are ok ...and not broken
dont know where yours is on the redtop but mine was on top of my manifold i have a blacktop

thanks for the input. i dont have a standard one so im now on the market for one so if anybody has one let me know.

Would it not work to just remove the dump valve all together? I don't think there is much need for them anyway.

ill have a look in a while. thanks for the reply

I have a standard dump valve here, if you're anywhere near cork...

i just had a good look at the bov and it seems fine. it does have a soft and hard setting. would that make a difference?

pm your way johnie

The soft and hard spring should make a difference, if you make it harder it should improve things for you some bit, but I don't think it will fix it completely. you should tighten it until you get the "pidgeon" sound at low boost and see does that make it any better.

If it was the dump valve and you checked for boost/air leaks you would hear air escaping out through the dump valve (I am assuming you pressurised the pipe work to check for leaks not just by looking at the joints and couplers)

like robbie said it ur dump valve a hks eids controller would fix this also

*cough jdm garage* Im joking sorry, I removed my dump valve ages ago, simply just replaced it with a new bit if pipe work, 10 minutes. I have some handy here aswell if your looking for some? Could do it tomorrow if you wanted even

Number 1 its Bunney! Number 2, Did I hit a nerve?

i had the same issue, its can be a combination of different things but as robbie said dump valve, can you take it off and run no dump valve to check?

when my car had fmic, dump valve, recirc valve removed, s15 turbo it would do same, there are a couple of things that will sort it. i used an hks idol stabliser which does what it says and i also used a couple of wee tricks with my intake piping. im not using the idol stabliser anymore so could sell it if you were interested.

edit: should really have read page 2 also lol, i see people are suggesting that the dumpvalve is leaking or spring is too soft? thats not causing it, its the fact that the air is being dumped when you lift off, air that has been metered by the afm that does then not make it into the engine causing it.

i also see connor has said an hks eids controler will sort it, thats the idol stabliser i was talking about, i have one for sale pm me.

i installed a hks ssqv and it fixed the problem so im sorted for this. it can be locked up. thanks for the replys

I have what sounds to be the same problem.

When turning a sharp corner or entering a roundabout (slow down and clutch in) the rev's die and it cuts out.

Takes about 10 seconds of turning her over before it restarts.

But i have no dump valve..... no intercooler.... its a standard neough blacktop.
It doesnt happen on a straight road and im 99% sure i dont have a boost leak as it accelerates fine, no hesitation etc.

Infact the car drives perfectly all the time...... untill you for example pull up to a set of red lights, turn a tight bend at 10mph....

Im lost and its doing my head in!!!!

Any idea's???

Still sounds like a boost leak! Check everything, joiners etc something could be cracked and you wouldnt see it till it moves

Isnt this car always in jdm garage when I pass if bart can't fix it no1 can ha. As he says Hese an expert on them.

@ topdog you told stacky in his other thread it was his fuel pump giving him trouble!!. Are u only going with the flow of Wat other lads are saying or do you just not have an idea?

If you read his other thread he give more of a description of the problem and states it only happens when his petrol goes below half a tank. If you read his threads properly you would have spotted this.

Off topic friday for the boost controller

this thread is 4 months old, its well sorted by now and it was the dump valve that was the trouble
