Meh, im putting my girl up for sale anyway - let the buyer deal with it.

I have noticed that it does it most often at low speed, in the first couple gears (when clutching), and when turning or just after turning. Maybe my power steering pump is sapping too much juice, or the aac screw needs to be adjusted to allow more revs...

I've heard rumours along the wire that a Throttle Position Sensor (TPS) can also be the culprit for an idle stalling problem. How do I go about playing with and/or replacing this?

I'll run a search, cos I know that's normally people's first answer (and it's lots of help, by the way... NOT!)

I might be on the trail to finally finding the gremlin. Have received reports that the TPS wouldn't be responsible for all of the things that I'm experiencing. It's more attributable to a sticking throttle body butterfly than a TPS.

So the next step (in this epic saga) is to remove the throttle body, and clean it like nobody's business...

I'll be sure to report in with the results - stay tuned.

Have you tried using another AFM I had this problem after installing the new Turbo was shitting me to tears trying to save it at lights all the time, I have a mate who owns a skyline and he just put a RB25 in his 4 door so weee spare AFM for the 20 anyway we put it on and presto fixed I dont get much stalling now but I think the rest just means a good tune

Ok guys i know how to fix this issue.

I tried everything to fix this problem on my R32

What i did was:

- Changed TPS

- Cleaned ACC valve

- Changed AAC valve

- Cleaned AFM

- Changed AFM (tested with RED top and SILVER top engines)

- Changed fuel filter

- Changed oil

- Played around with the idle screw

- Cleaned out throttle body+butterfly

- Cleaned plugs and re-set em

- Checked for vacume leak

NONE of this worked at all!!!, i was spewing.

But finally i was looking around the engine bay and spotted the

COLD START SOLENOID.

I got a new Cold Start Solenoid from my mechanic and it was fixed!!!!!

Finally!!!!!.

It doesnt hunt for revs anymore, and it doesnt idle high.

It purrs like a kitten.

PS: I talked to my mechanic and he said that skylines engines are pretty prone to stuffing up the Cold Start Solenoid.

This would be ur problem too. Id start there ASAP cos you dont wana go shitten around trying stuff that dont work, like i did.

Hopes this helps you guys,

Matt

I've fixed the stalling problem!!!

It was the blow off valve. Which is very strange, cos the blow off valve I had on it was the Greddy Type S, which was being plumbed back just like the stock one. Maybe it was blowing-off too early, too late, too much, too little, too who f*cken knows...

The good news is she's not stalling anymore, and I'm smiling again!

The cold start solenoid is located under the intake plume cross over pipe (between the intake and the rocker cover) you may need to push some wires/pipes out of the way. Its a square thing with tubes going into it.

I got a brand new one from japan through my mechanic that cost $190. could try and get a second hand one but usually they are f**ked with the same problem

Cheers R32FOURDOOR..

I Didn't get chance to check forum on weekend, so in the mean time, I did something else.

I reset my computer by disconnecting the battery and pressing the brake a few times (to clear any remaining volts) then plugged it back in... I couldn't tell if it solved the cold start problem, but it doesn't seem to be rev hunting at idle anymore.. it's actually quite smooth...

      Just don't use ChatGPT or any other artificial stupidity for the equivalent of googling. Their demonstrated inability to discriminate reality from hallucination should be enough to make them totally untrusted. LLMs don't know anything and cannot think to even the smallest extent. They are just predictors of the next word, and that should never be confused with capability.

      Another little story of weird shit happening

      By GTSBoy · Posted

      I think, given the usage model described in the OP, I'd never ever experience the wonders of the 400kW upgrade. What I really need is boost from 2000rpm and probably no more than 260-270rwkW. But I suspect that the highflow is not actually the turbo for that purpose, so I may in fact need to get a G25 or 30 or something right sized and very spooly. We shall see after it is tuned. I've had to back the boost and boost ramp off to stop the thing from pinging since the highflow went on, so I've been almost living the NA life for 9 months now! Injectors are recently in hand. AFM is in hand. Dyno is fixed. Just need to clear a queue of f**king Supras out of the way (and probably fit my new gearbox). So....some time this year? Lol.

      braided lines for the turbos

      By GTSBoy · Posted

      For what I gather is a Sunday/summer car....braided is fine. You're not going to be left without a vehicle and you have plenty of time for inspection/maintenance. Oof. I wouldn't use them that way. They can probably handle the temperature** but the internal corrugations means that their flow characteristics are a bit shit. Lots of extra friction and pressure loss. Makes them flow like the next pipe size down. ** They are stainless, and the stainless can usually be at least something like 304L, which is pretty good at higher temperatures (unlike 316L, which I would use for a wrt/corrosive environment, but not a particularly hot environment). But the welding needs to be top notch. And even then, because you usually need at least one cone-seat end on them (because you can twist the hose and do up both ends at the same time unless one of them is a union) they can be prone to coming loose with heat cycles.

      braided lines for the turbos

      I don't have the OEM oil feed lines though and the turbo-wraparound line is torn, only has water. My plan is to get replacements for these and just connect a braided line to there. And make sure it's leak free. Hoses like these are also sometimes used to connect external wastegates, so for an EGR I think you're good using them.

      Alright I understand. The most likely case is probably gonna be that I just keep the OEM unit in the car as long as it works.
