can anybody please help? my car has now developed quite a bad misfire under any condition, it almost feels like someones turning the igition on and off? i was told air flow meter. any other options? ive had a look at all the coils and they dont look cracked, also the car was plugged in at nissan this time last week, they found a loose wire on the afm plug, fixed it and it went smooth again but seemed very sluggish to me. now its misfiring badly. does everything show up on a consult check or can things be missed? also is there anyone in victoria you guys would recommend other than nissan (who dont seem to know f**k all! :laughing-smiley-014: )

What other symptoms does your car have? It's probably something simple....

If it's misfiring under boost then it could be spark plug gapped to big or coil packs need replacing. If one of the afm's are dying then you'd notice it stalling sometimes, and hesitating sometimes....

There is a sticky with recommended workshops you should look at, but I'd recommend Racepace in Bayswater if you want a GTR expert.

cheers for your reply, it started with a few coughs at idle and the odd mis when driving, nothing major. then it was stalling and it would try to recover and hold at about 1300rpm, took it to nissan and a wire on the afm plug was broke, they fixed it and it ran smooth and no more staling etc. now about a week on this seems related but different. first noticed it waiting at red light when it decided to idle between 100-200rpm didnt stalll but didnt try to recover either. gave it some gas n it went away. knew something was wrong though so all week i have just been taking it easy now its cutting in and out all over the place from a little misfire to fully cutting out for a second? did it the whole last 5 mins that i drove it tonight. so shes retired from being the work taxi for now;) also note the car has no mechanical knocks, taps etc

boost leaks dont show up on consult, neither do blown headgaskets, dodgy wiring, you get the point

if used properly it can rule out a lot of things though. best to get ur hands on a consult cable and do it yourself (then u can post logs etc here, as well as check fault codes)

ok took the day off work! pulled out both afms, they looked fine but resoldered them anyway and also took out all the coils and sealed the outsides with the selleys 401 silicon. put it all back together and the car goes good as new, so cheers heaps for your help!:mrt:

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.

      R33 GTR running -9 with no tune

      So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.

      Squeaking clutch/throw out bearing

      Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.

      It ended up being that orientation of the float hub in relation to the clutch disk, when I installed it, I heard a loud click and being stupid, I decided to not take it a part and check it. The hub didn't properly align with the clutch disk and was causing the issue. Definitely an odd one! Dahtone Racing was able to fix me right up, stand up blokes!

      By joshuaho96 · Posted

      Right, but I'm saying on the stock ECU measured airmass from the MAF is no higher than stock. So it's accounting for the higher flow rate iso-manifold pressure. You just have to keep turning down the boost until you're within the stock tune's load scale. If you run off the end there's no telling what will happen. This does mean there's zero benefit to the turbos you're running vs stock, if anything it's just a straight downgrade because the transient response is worse, you don't even get the ECU's boost solenoid helping to pull the wastegate closed during initial spool, and peak power is only whatever the factory map can give you before you hit the R&R corner. On a -9 I would bet that you would have to change out the wastegate spring once you have a real ECU and you're tuning it for real. I'm not saying this is a remotely ideal state of affairs, it's just a way to keep it driveable until you can get a proper tune done.
