Ok, heres the deal.

My gtr is stalling on idle, spluttering etc only when warmed up.

Thought it to be a ECU issue with the power fc(Which when installed happens alot more frequent and worse) so i got the old ecu installed worked fine for a week.

Issue still exsists.

I have checked the Vac Lines and piping for leaks as far as i know there are no leaks.

I have cleaned the AFS with contact spray.

I have yet to check the Idle control unit.

I run a stock bov.

The car use to idle on 1200rpm however after issue only appeared after idle down to 9000/1000rpm from Godzilla after they fixed my timing to 20.

I have taken my car to Mercury and they did say it was either the Power fc or the wiring.

I got my stereo installed by WOW @ Underwood. Dodgy install dodgy products drivers side speaker blew and they tried to say i installed it myself (I Didnt)... anyways back on track when the car stalls it does not seem like it looses power the engine just dies could the wiring be stalling cutting ignition to the engine?

I have been told that it is a common fault with skylines that it does not return to idle very well. or that the altnerator does not charge correctly.

Can anyone help me?

Sounds like an airflow meter to me, try swapping them one at a time for one you know works, While yours are now clean the fault could be on the solder inside it for example or like mine the wiring in the pug has come loose from the pins

Thanks mate, Yeah im taking it to a Auto Sparky tomorrow to get him to have a look at it.

Cheers for the tip.

I thought it was the power fc looks like i can plug that back in :thumbsup: as soon as this is resolved lol.

Wiring is fine, Suspecting a DEAD AFS. or its not earthing right, so tried some stuff and if that doesnt work new AFS will be coming.

Hey mate go to the ETC on your PFC hand controller and select sw/sensor - you will see o2.1 and o2.2 listed check what these are reading. They will be different but if one is way different to teh other tehn you can confirman AFM prblem.

lol. thats all i have to say to that claim.

So are you saying that after WOW installed your sound system, the car THEN went funky?

Can you give some advice as to how the events unfolded in chronological order?

I remember I had to adjust my idle thingy on the rb26 and all i can say is DONT take it off because it is a broad minded person to get back in. If you adjust it with a screwdriver, it may work for you, though I don't know if that is just a bandaid solution - still masking the original problem.

Jonnyo's postulation seems quite logical, if you dont have access to a multimeter - id give that a go first, since it is a non-invasive procedure.

Otherwise, good luck.

When I first got my R33 a few years ago it used to hunt like mad and sometimes stall when pulling up to lights and stuff. I searched on here for similar problems and a few people managed to fix it after cleaning the idle air control valve. What happens is the spring inside gets all full of shit and doesnt open and close properly causing the car to hunt at idle. I took mine off and cleaned it all with carby cleaner and then adjusted the idle and that fixed the problem. Easy game.

Here is the link to the guide I followed.

AAC Valve Cleaning Guide

This is done on an RB25 but there isn't too much difference between the two engines anyway.

Thanks, I just adjusted the idle and it hasnt not hunted since ;)

if its still playing up re-install stock ecu and hook up a diagnostics tool to it, ask mercury or what ever shop u use, one should have one and it should be able to pull out a fault code, letting you know exactly the fault, my guess will be afm's most likely. very common problem, they just get old solder inside them and can be repaired, but most people exchange them or buy new ones at great expense. butr could be another issue with iac aswell? try them all, just go to the diy section and start searching for HOW TO: threads. its a process of elimination with skylines.especially when it comes to sensor problems, some or many may lead to the same out come, its just trying to find the correct one which is a bitch.

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
