hey all,

while driving on the freeway in 5th i was half booting it and all of a sudden.. no power, nothing the car just cut for a split second then kept going feeling abit sluggish (could be paranoia) but didnt feel right. stopped at the lights later and then the car stalled. i started it back up and it was all fine. drove it home and it happened again like the engine was compeltely non responsive howevr this time it died. i pulled over and then started it again and it worked fine.

This all happened again today so i dropped it into the mechanics just to be safe and he says its my afm, and it will cost 400+ to recondition. could this problem be anything else like coils or something? and if it is afm would the tutorials i found on soldering etc be relevant?

thanks for the help

it definately sounds like AFM, but dont pay $400 to have it 'reconditioned'. You can try getting some electical contact cleaner and cleaning it with that, but you should be able to find a 2nd hand afm for < $100.

the poor performance could be due to coilpacks causing a miss, but the stalling and hunting is indicative of an AFM problem.. Plus the fact your mechanics said the same thing certainly points towards it... Only way to see for sure would be a CONSULT hookup.

I don't have this problem but i recently swapped mine out and sold the old one.

It was working fine but had a lot of greasy build up in there.

CLEAN IT YOURSELF GUYS.

If you've never seen one, the actual sensor part of the filter looks so small and delicate I'm suprised these things atcually work! :/

Get a can of contact cleaner and spary to your hearts content. Leaves no residue and heaps of crap will come off.

You're safe to spray the wire sensor too.

Pics here of one removed : http://people.aapt.net.au/~jason1973/Ebay/

To remove the AFM will take a good 5 mins with 4 bolts and 1 hose clamp.

So even if you've never done anything mechanical in your life, this is a good place to start.

$400 for a recon!!! I bet he would do the same spray i suggested, what a rip!

Brand new Z32 is around $350 for goodness sake.

(By the way, i sold mine, working, for $50)

      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.
