Hey all :)

I have a problem with my skyline. Only occasionally I will start it and begin to drive.. then when I'm accelerating it seems to lose power and slightly "bunny hop" the bunny hops are not aggressive. it just doesn't seem to be able to get to higher revs. It does happen when it's cold but by the time it's warmed up it still has the problem.as I said it only does it every now and again. Does anyone have any idea what could be wrong?

No mods except for a coke can in the blow off valve (bought like that) :P

Don't know the service history from previous owner. Has had a complete full service. Was happening before I recently got it serviced.. mechanic changed the fuel filter and spark plugs (thinking they were the cause) but problem still persists

It happens at any revs. It happens whenever I accelerate

Found this thread and am bumping it because I have a similar problem. I'll describe it in more detail though.

This happens occasionally, and only early in any drive if it does. Not like right out of my garage but 1 or 2 minutes in. I will probably happen at a frequency of about once every 3 times i drive the car.

Once it happens it will happen until i let it sit out of boost for a while and it will be ok. I even did 5 runs at autocross after this, problem did not crop up.

How violent it is depends on how much throttle i'm using. If I hold it down as i'm trying to accelerate and not let it if it reminds me as if someone who is just learning to driving a manual is driving the car. Off-boost it doesn't do this. It only does it at RPMs in which the turbo is building or holding pressure.

Same recommendations? I don't have another AFM to try otherwise I would but I could install my powerfc and put in a Z32 AFM.

I had an r32 gtst back in 2004 which would do that, the car would lurch back and forth violently under acceleration. Turned out to be a really dirty fuel filter, wasn't allowing sufficient fuel to the rail so the car was suffering fuel starvation. Upon reflection I'm surprised I didn't destroy the engine, must have been running ultra lean during those periods.

Did it do this all the time or only occasionally like it's doing for me?

I would think if it were a fuel filter it wouldn't just stop and be fine for hours.

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
