pull out your spark plugs again and inspect them. that will give you an indication of whether it is a fuel issue. if they are black then it isn't a fuel issue but a spark issue. if they are a light colour then it is a fuel issue. if possible get someone to drive behind you and make it play up. if they see unburnt fuel coming out the exhaust when it missfires then you know it's a spark issue.

legend. will do

how much boost you running?

i have a similar issue and i thought its just the stock ECU fuel cut or R&R, if i reset the ECU it will be fine for a while....

how long was a while.. what did the final problem turn out to be?

generally if the fuel pump is playing up it will usually only be in the high end where it starts to lean out. generally it should be fine at lower rpm as the fuel being used is very low so the pump should be able to flow well enough.

wouldn't hurt to replace it to be on the safe side, however if it isn't the issue then you have wasted a few hundred dollars. you would be best off putting the car on a dyno to get the AFR's checked to see if it is leaning out. that way if the AFR's are fine you can put the money towards finding out exactly what is the cause.

I have no idea bro, sorry. Man, I'm sending the car to a dude in Melbourne that comes highly recommended. Supposed to go today but had a wedding I sorta forgot I had to go to. I'll go to him early on Monday. If he tells me the cars problem, I'll pass that on to you, or if you're in Melb. tell me and I'll give u his details.

the dude fixed it in 15 seconds. f'ing very good guy.

#1, the turbo we changed was boosting (or trying to at least) at 22psi,

#2, the afm was dodge so i replaced with the another standard one,

#3, the loom that sat in the afm was pretty shockingly crusty, so we changed that and he crimped it into place,

#4, the bov i had on the car was pushing a lot of what was in the pipes out, so the sensors got crappy readings and made it try and cut out,

just little bits and pieces. the dude did a massively good job, anybody in melb who wants serious work done to their car should go there.

i hope some of these steps help u in ur problem cuz.

good luck.

      Shoota's R33 GT-R RB30/26

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.

      I always use my Karcher, but it's only a little one that I picked up from Supercheap  The only issue I ever had with a pressure washer was when I was a kid cleaning coaches, they had a hi-po industrial sized petrol jobbie that would strip paint if you got to close I saying this, we have a fairly high power washer at work with a diesel powered heater that sprays water at about 60°c, it works great for removing old wax and road grime on the underbody after some foam cannon action, albeit from a "stand off" distance of a few feet

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!

      Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.

      Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.
