There's plenty of components that could be helping out there.

It does sound suspension related if it is ok unless going over bumps.

Might be time to change the bushes or something like that.

Pretty cheap if you just install pineapples to make it tight again.

Check for wet or oily patches in the general area around the subframe.

If it isn't suspension related, perhaps something simple like a tailshaft bracket has come loose.

Or it could be something dodgy like your exhaust is hanging loose.

Either of these rocking at high-speed would amplify the effect of the wobble.

Depends what you are feeling. Wouldn't hurt to take a quick look to rule these out.

You should be able to give it a decent overview yourself - from gearbox back.

Try and shake everything by hand and if anything moves, that'd be the first place to start.

Once the initial check is done, best to get it onto a hoist and give it a proper look, especially if it is influencing hi-speed control like that.

Should be easy to rule out wheel bearings if you aren't hearing the low hum noise at high speeds.

If you drift, then who knows.

Might just have to take the trusted mechanic for a spin and see what they think.

Oh - Does it feel like your suspension is bottom-ing out ? Perhaps just need a new set of springs, or if there is oil running down your shocks, perhaps time to get a new set of those.

Hope this helps.

Don't mean to hijack or anything - related really - but what the hell are pineapples and what exactly do they do?

I have heard about them, seen pics of them but just lost on where they go in the susp. and their function...

Seriously just take it into one of those pedders suspension checks... Cheap and your not obligated to have any work done afterwards.

Probably the quickest way to find out what the issue is because as above it could be numerous things.

Thanks PappaDuck for all your help.

I can rule out anything being loose now.

The car has got pineapples.

When I think about it more I think it is suspension related.

The front end has to tendency to bottom out going over bumps and makes a loud bang noise.

If i remember corrrectly it all seemed to change after one drifting eposide. Mates have told me the rear tyres look wobbly and it kinds feels likr that a bit aswell.

I'll put it on a hoist and see if i can find something wrong with suspension.

mine is doing the same thing. are you hearing a sound like something is hitting something else. like metal to metal, my left rear strut is blown and as soon as it went out mine started hopping left. its scary feeling. check and see if your struts are good. im replacing mine and ill let you know if it fixes it. also yeah what are pineapples

      Yet another RB Neo misfiring thread after reading all the others.

      Good tips, will get on those tomorrow. When doing the maintenance I did move a few of those connectors around, and things that are old tend to not like moving around. (Like me).

      Don't try it. It will be shit. Better chance of damaging the engine than gaining any knowledge about the old one. Maybe, but unlikely, especially if the O2 sensor is working. You can use NissDataScan to look at the stock ECU.   Cleaning the AFM is seldom necessary and seldom helps. The R35 coil & loom conversion should eliminate dud coils or plugs. But as you still have misses - look to the plug where the coil loom connects to the engine loom, and the CAS plug. Need quality connections there. Also look to injector plugs. And the AFM plug while you're at it. Also look to whether your injectors are clean and flowing evenly. Get them out and onto a testbench.

      Good to know, I feel like I am in for a rollercoaster ride that looks like a sine wave.

      Hey folks. I've been lurking and browsing the forum for a while, since I got into my head that I wanted a skyline. Having purchased an overpriced completely stock GTT, (only "mods" it has is HKS pod filter and catback) now that it became legal in the US, it was all glorious and sututu noises here and there. But then I wanted to do things right and went to do basic maintenance. After all the fluids, filters done, I did the spark plugs, that's when the problems started.. First the car started spluttering at around 4.5k RPM. Which I gapped down the new plugs and that solved the sputter there, but the car now always misfires at idle with pops when lifting off and shifting 2nd to 3rd. Similar to the issues in this recent thread. I've been banging my head against the wall, reading the threads here and trying suggestions for a couple months now, so decided to start this one to explain exactly what I tried and what is going on. The symptoms of the issue: Idle and low revs misfiring intermittently. You can hear the exhaust tone change and the shakes on the shifter knob. It happens frequently, but doesn't seem to have a rhythm to it. Pops when backing off throttle. It pops and or burbles almost feels like it spits fire when it pops. (Happens mostly in 3rd gear at around 2k RPM). When under load and after 6k RPM, it also pops when shifting from 2nd to 3rd. There's a ticking noise at around 2k RPM in 2nd gear going downhill, seems unrelated though but I am out of educated and downright dumb guesses. Not noticeable lack of power when putting the car into load. The attempted diagnosis and solutions: Unplugging coils when the car is running This did nothing to change the idling and tone shift for every cylinder. Checking the exhaust headers with thermometer They all are within what I'd say it is margin of error of the laser thermometer New spark plugs Tossed two new sets, copper, iridium and using the old ones, still misfiring, even re gapped to 0.8mm, still same thing. MAF cleaned with the "specific" spray cleaner No changes in the issues what so ever. Brand new loom and r35 coil conversion (was going to add the r35 coils anyway) car runs arguably better, still misfires, but seems like does less frequently. Placebo? Code 21 now being thrown, thanks nissan gods. Removed the CAS to check the shaft for play or anything. CAS seems all fine, nothing that indicates any issue, visually speaking. Things to attempted next: Ordered a new MAF (chinesium from Amazon, to be able to return regardless of result). Fuel with proper gas, maybe it is this California water that they sell as gas that is to blame? Plugin the link ECU and check the info using the built in base map. Go back to BMW and eat my rob bearing breakfast without milky oil mixture.   Do any of you have experienced anything like this or have any suggestion?
