Hey guys,

i've been having this problem for a little while now and i was hopeful if anybody here could help me to pinpoint the problem?

Sometimes, when im driving along, the car will cut out and stall all together..

When i turn it back on it does this:

When i turn it back off, and on again, its fine ..

I was thinking maybe its a shoddy alarm installation?

I tried changing pods and cleaning the AFM.. could anybody help me out?

Car has a stock BOV, happens every so often and i dont know how to re-create the problem to show any mechanics! :bunny:

mine starts idleing like that as the alarm imobilisers kick in.

i have one of those brant pin pad alarms. it has a highjack setting.

once i get in the car, start it, close the door and put my seat belt on its enabled. so once any door is opened and my seatbelt in un-buckled after 40 secs or so it starts beeping at me and then the car cuts out

can be a pain sometimes...took me ages to work out when i first got the car...even took it to an auto elec and he didnt know.

I'm going thru the same problem as we speak.

A few mates have told me it could be a range of different things including air flow meter, fuel pump, coil packs, spark plugs, dirty throttle body blah blah blah.

I have an R33 RB25DET - very low k's so i don't think its the coil packs, i changed oil, fuel filters etc, i've taken it to a few mechanics and coincidently it runs fine and there are no errors that come up. Today i changed the spark plugs and it made a huge diffrence, now i can actually drive it up the road before it cuts out and starts coughing and spluttering. The spark plugs were black and smelt like fuel so its running really rich. I'm gonna get a new airflow meter bolted on next week to see if that's the problem - i'll keep ya posted.

If anyone else can help that'd be great. Even just some direction on what to replace next or even some suggestions on who i can take it to to get fixed around the Wollongong area. I'll take it to Syd if i have too.

Good luck

My r32 stalls like that once or twice a month... I still haven't figured it out. No codes, it just dies. Some times it will start up and be fine, others I have to sit and wait 30-40 minutes before it will start again. Not sure if it's related, but I can't get the timing lower than +25 even with the cas all the way ccw.

New fuel pump, new fuel filter, cleaned injectors, new fuel pressure reg, new ignitor, new battery, new spark plugs, borrowed coils from another car, new ignition loom, new (used) cas, new (used) ECU, new battery leads, pulled some extra earth leads, tested alternator, cleaned every electric connector on the car, clean & resoldered afms, cleaned aac, compression tested, boost leak tested, tested almost every wire in the loom.

Nothing helps. I'm so frustrated with it that I'm going to sell it next month if I don't get fix it.

Sorry to rant in your thread! I hope you have better luck than me!

i would be looking firstly at the IAC and AAC valves. they control the idle IAC, as well as the idle when things like the aircon is turned on or the steering is turned and more load is put on the engine at idle (AAC). these valves often get dirtied or blocked by carbon and don't operate properly because they become sticky. this is why sometimes turning the car off, or even just giving it a rev can be enough to make it idle better as you are making the valve move even more which can be enough to temporarily sort the issue out.

i'm guessing that isn't your car in the video and you are just using it as an example of what the car runs like? if so then the above is what i would do. if it is your car (even though the video is from october 08 and plenty of people have said what the problem is in the comments) then i would plumb the bov back in to where it's supposed to recirculate to (between the AFM and turbo) and that will solve the issue.

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

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

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
