alright guys its been doing this since last week and now its getting pretty annoying cause i'm a noob and i ahve no idea what it could be lolz.

the car is all good when i start and everything...car runs normal and so on..but every now and then the car will just seem like its engine braking or simply losing power for about 2 seconds then it goes back to normal. during these times i'll still be on the accelerator and it still loses power. the car doesn't switch off or anything..it'll just go down in revs abit then go normal again. sometimes it'll happen when im clutching in to slow down and at this point it'll drop down the revs till it stalls.

i have a feeling it might be a faulty afm? or could even be my spark plugs? but i wouldn't have any idea on how to check. if anyone can tell me how please do.

otherwise if this sounds similar to what you ahve experienced or are experiencing please tell me what u think it might be and i'll check it out. thanks

my r32 does the exact same thing... sometimes bad, sometimes just jolts a bit and carries on.. feels like its running out of fuel.. im pretty sure its the afm, as i can feel it change from the afm to 02 sensor at 2500rpm, runs smoother, but can still muck up at higher rpm, but ive had it before where it wouldnt let me past 2500rpm, just hit a rev limiter.

saving up for a safc so i can get a brand new z32 afm.. will also change 02 sensor and fuel pump for shits and giggles.

breaking news...drove to skool today and it didn't do it at all?

really weird...i have a feeling now that if its not any of the other usual suspects could it be a bad batch of fuel? maybe fuel with water as they have reported on the news?

cause i filled up with bp the week it started happening...yesterday filled up with vortex and it didn't happen. i'll see what happens on the way back home if it does it again..if it does i'll know it can't be fuel.

could it be a bad fuel issue

sounds exactly like what happened to me, and it was AFM.

Get your hands on a working one and borrow it for a little bit, see if it does it again. If not then you've solved your problem. If so, then you know to keep looking.

get this... my car drives fine for the 1/2 hour trip i do to work everyday... not a problem... come night time though, when me and my g/f go for a drive, it happens all the time... cant boost it or anything, freaking annoying, just dont think the car likes her, which is fine with me, she is taking up cage space.

check the afm wiring, that its not shorting out somewhere.

cheers

hey man this sort of thing keeps happening to me too with my r33. well now i've actually figured out how to actually stall the car. its not random. try this alright:

when you are 4th or 5th gear, boost the car a little bit to gain a bit of speed. then let put the car in to free gear(neutral). if it stalls or rpm drops below normal you probably are having the same prob as me.

think it mite be something to do with the turbo winding down or BOV settings?

that would be your BOV... I have r33 that does the same thing, ive adjusted the bov and it helps a bit, but still does it once or twice. I cant get my hands on a stock bov which is even more annoying.

      Slight brake pedal stutter after new pads

      By MBS206 · Posted

      Jack the back of the car up, pull that wheel off, pull that sensor out, and put a bore scope into the hole to inspect the outer casing, see if anything looks damaged before you pull the whole thing apart.

      Ergh... So I pulled the speed sensor out again and the tip was shiny so I think it's rubbing the bearing. The bearing contains the magnets for the speed sensor so I think when the first sensor broke it damaged the magnet ring on the bearing.  This is just a Google image, but there is a hole going to the bearing. So when the tip broke off the old sensor I'm guessing it fouled the bearing... As the magnet is only protected by a plastic cover it would be easy to damage it. So I guess I'm doing a bearing again.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol
