* DUE TO CONFLICTING OPINIONS, THIS MAY OR MAY NOT WORK. IT HAS FOR SOME, HASN'T FOR OTHERS*

This came up a while ago and I have had the same problem since I imported the car 6 months ago.

Basically when cold the car won't idle up on its own, you need to stab the throttle then its fine. When its warm its not a problem.

I went through the whole lot, cleaned throttle body, AAC, air regulator, Plugs, packs the works.

Today I bought a new battery as my old one was shagged, the new one is a Bosch Silver series, pretty bloody big, just fits on the battery tray and had to make up new terminals and such. Cost $99 on special so not a cheap one.

Result? Car fired up straight away and idled up perfectly! No throttle needed and it turned over in half the time it normally takes. I have'nt driven it for a week either so this was certainly the test.

It seems the ECU needs max volts to operate the cold start properly. The previous battery in there was about half the size of the new one, its a brute!

Definately worth the 100 bucks as I think many cars, especially with most of us running fairly serious stereo gear can benefit from the biggest battery we can fit in the space available.

Good luck!

Hey my car has the same issue, never thought of it as a problem though, just a little quirk.

Maybe ill get a bigger battery next time.

Thanks for going to the effort of doing the research.

I've got the same problem.

I suspect its my injectors. I've replaced battery's etc.. no difference, does spin over quicker though.

Mine doesn't always do it but most of the time it does. Within the pfc controller if I richen up the water temp compensation for cold start the idle stumble goes away.

So mine appears to be fuel related.

You think wrong. hehe :rofl:

On the stock ecu, mine stumbled and spluttered exactly the same. Exactly.

The only way I have been able to get rid of it is to richen up the water temp fuel compensation tables once I got the PFC.

I've heard other R32's with stock ecu's stumble splutter, I've also heard other PFC equiped R32's stumble splutter then a stab of the accelerator brings her to live.

It appears to be something other than the ecu, battery etc. I think it is fuel related. Remember mine didn't 'always' do it but 90% of the time. Once it even went a few months starting perfectly then it went back to its usual splutter.

Maybe its an earth issue, playing with the battery has temporarily fixed it. :P

I'll update as I go but it started perfectly this morning :rofl:

Someone else a while ago suggested it as well as a new battery fixed his.....

Maybe the stock battery terminals are stuffed? I changed mine to huge gold plated ones.

Either way, its worked for me so far so if its goes back to its old ways i'll be back ,:P

hmmm bizzare.

All I know is it works for me so I'm stoked :D

Maybe Nissan will hold the answers?

Did you replace it with a bigger battery? Maybe the batterys are undersized in them?

Who knows, did'nt hurt though cause my battery needed replacing badly. WOuldn't hold charge for more then a day.

Well i went out on my day off and shopped for batteries, but ended up at super cheap wiht a Bosch Gold Series one, cos me 89, ten Bucks off.

Thing is tho it was taller, lil, well the Terminals are form the top, not sunken in like the stock batt. The Wires with teh battery terms. were too short. arrrgg

so i used some big arse amp white and attached to the old bat climps and then attached new ones to the ends of amp wire, seems to go fine, haven't had teh moring test yet, that is tomorrow.

I got to find better way to joint that big arse wire so i 100% sure i getting percet connection.

If got any ideas on the joining let us know.

Anyway i let ya's know how all goes.

Later,

haha Thats bodgy as sh*t. :D

Head down to supercheap or where ever and grab a nice new big fat earth wire.

Thats one fixed.. Unsure what to do about the other one though. :D

I replaced it with a 480cc Excide thing with a nice little window to see the condition of the battery. It spins the car over rather quick.

      Stock rb25det neo questions

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
