R32 Rb25 Idle Problem

[mafia]

hey Im having problems with my idle on my R32 RB25DET. It has kinda just progressively just started happening. when i bought the car it never had idle issue which was about 6 months ago but in the past couple of months in has kinda just started. In saying that most days when you come to a stop the car will just cut out but on other days the car will nearly cut out and then rev high and then idle normally. but on a good day.you can never tell if its a good day or not though.haha

I have check all my VAC and boost lines and i cant find any leaks anywhere. Is there any other lines that I should check or replace?

I also read up that if you giggle/unplug the throttle position sensor the car should cut out, but mine doesnt seem too.it keeps running. i have just kinda adjusted the throttle position sensor to keep the revs high today and its all right but ovcourse way too high for what it should be but is that something all right to do for the time being?

should i also spend the time and check all the Coil packs?could they be causing this problem?its problem worth just to check em right.

another question is I have 3 X RPM counter. One dash, one Apexi rpm/speed meter and another one that I got with the car but too ashamed to name so ill call it the unknown.anyway the unknown and the dash RPM are the same which shows like low revs compared to the Apexi one.which one should I take seriously?haha

the Apexi gives more real revs i think but im not sure.

I have attached 2 phots the first one is of my engine bay and the second one is of my BOV line setup.

Do i have to modify these lines to make my boost/vacuum gauge read Boost and not the vacuum?

thanks in advance for your time and help :)

does it splutter as well? i'm still having similar problems i've ruled out the ecu coolant temp sensor, and i've done a half assed job on cleaning out the aac valve . do a ecu error check there's a thread in the DIY section

[mafia]

it kinda splutters and sometimes small backfires when you rev the car.

with the aac valve there are no wires or anything plugged into it so I havent bothered cleaning it yet.maybe I should try that.

I was going to try that.look like I might do it cas not much input from other people haha

cheers man

plug it in, that should be the problem

learn to heel-toe on traffic light/stop sign stops

why's that, using r32 engine loom and you do have the plug but only for the r32 unit ?

try CRC contact cleaner on the AFM and reset ecu, has made mine stall less although it does still stall at stops here and there this makes it seem like a combination of things.

ps. ment to be general maintenance but if your fuel filter is old say a yr old change it.

haha funny that you say that. I have been doing that the last couple of weeks until the last couple of days.my gf is like u should have to drive like that but i was always like its fine no problems.haha yer im not really sure why I have no plugs for it.there is one small one that i Tired fitting but didnt work. I called the dude that tuned it and he said to bring it in but I really cant afford to bring it in for something like this.

yer catch to that is I dont have any AFM but the car has been running fine until the last couple of weeks.i just hanged my fuel filter 4 days ago and it didnt change anything.
