Hey Guys,

This week while driving i was on the highway and the car was running fine i then took an exit and was going doing 60 down a local road and my car started misfiring and carrying on so i went to pull over and the car stalled. I then waited a minute got the car to start and got it home with it misfiring and acting like it wanted to stall the hole time. Once i got it home it sat for around 20 minutes and then i started it and held it at a rev as it was still playing up and it seemed to stop whatever it was doing and drove fine however on and off of most trips ive done this week it has continued to have these mifiring spells and then when i seem to wait around 5 minutes the car runs perfect again!?

Has anyone experienced this i cant figure out whats causing it other then the thought of a faulty wire in my harness.

Regards,

Dan

Could be something clogged in the fuel system? Run a bottle of fuel treatment like injector cleaning stuff, and maybe take the coilpack cover off and see how that goes?

Stalling and idling like that usually means (if everything else is ok) some sort of vacuum leak. Check all your piping, it's possible that one of them is cracked or something, and with heat, it expands.

Hey man these people are only trying to give you some ideas to what could be wrong, any mechanic would only suggest the same without actually looking at the car and seeing what its doing and etc etc. to me what they have said sounds like a start and if none of these is the cause then at least you know what its not.

I had the same problem and still do ATM but car is off the road now. I knew i had a dodgy Fuel Pump cos it was running lean, and then all this started to happen, So i now have a new/bigger fuel pump and also a Z32 AFM being installed this week which should sort the problems out. I have also heard that the pipeing could also be a issue, but i'd start with the fuel pump if i was you!

Ive got a 500hp fuel pump that i havnt installed yet i guess its time to make the change and find out. Although i was talking to a guy at work who got fuel at a caltex same as me just last week aswell and ended up dieing half way down the road. He got towed and they emptied his tank and found that there was 20litres of water in the 50 litres he had purchased. So im wondering if i to got a batch of this shit fuel.

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
