If you have HICAS, then it's LSD. Most likely is AR-X models, however the lucky few have it as an option on the Rs/Rx.

The throttle reset is tricky to get right. Go through from the begging, ecu reset, throttle position learn, and then idle learn.

I'm giving the stag some love this weekend - will be cleaning throttle body (idle reset procedure didnt work, idles at 1400 in N), doing fluids in transmission, attessa and diffs. Do the diffs require LSD fluid?

Cleaning the throttle will only make it worse, make sure there are no vac leaks (the PCV hose is a common culprit) and no engine lights as it doesn't set the idle with an error present.

Change the transfer case fluid too. ;)

Oh - I read some posts on other forums where cleaning the throttle body helped get the idle reset to work. I'll pull it apart and have a look, but i'll be much more cautious after what you've said. Will the check engine light be on in normal driving if i have an error?

I sprayed aerostart on a few hose ends but didnt get any flaring, so couldn't find a leak that way. There is vacuum at idle, so if there's a leak its not huge.

For me attessa = transfer case, so that's in the list. Might do power steering fluid while im at it.

PN-MAD - I went through "Accelerator Pedal Released Position Learning" and "Throttle Valve Closed Position Learning" first - is that what u mean or is ECU reset different?

Yeah, that's what I meant.

It's pretty obvious when it does the idle learn. When hot, it revs up to 1800 rpm, then drops to the point it almost stalls, then goes back up to 600-650 and steadys. It can be hard to nail the timing, but it does work.

Last resort is get Nissan to do it with consult.

So I think I worked out why my M35 keeps throwing the code 1320. I took the coil packs off to change the plugs and half of the plugs were covered in oil on the outside. The tubes look like the seals are leaking and oil is getting past the O rings in the rocker covers.

Has anyone else experienced this? And where would i get rocker cover gaskets and the o rings.

Yes, it's very common.

But oil is an insulator, so shouldn't effect the coil packs. There is two ways of sealing. First buy whole new rocker covers. The seals are integrated. Or, two, try copper seal or something similar on the rocker covers to try to seal them.

Btw, wrong thread?

FYI - got the idle procedure to work - now idles at just over 600, and is completely smooth. Much better. Hopefully ill get more than ~300kms a tank now.... If not, ill swap the o2 sensor(s). ECU code was 0000.

Transmission fluid looked fine on the dipstick so i had thought it was probably ok, but when I dropped it, it was brown (not too dark) and stunk terribly. The transmission sump plug was completely clean, but ill do the transmission fluid again after say 500kms since its only 4 out of 10 litres from the sump each time.

Just get the Transgo shift kit done Stabby, it changes most of the fluid in one hit and is a must do mod for the M35, along with the brake wire cut. It sounds like the trans has been cooking, was there much red powder in the oil pan?

Not sure about red powder - i just dropped the fluid not the pan. Is the plug magnetic? Is the red powder metallic?

I'm trying to NOT mod the stag since its the daily. The GTR is for that stuff. Would you recommend the shift kit and brake mod for all use modes?

Edit:

PN - yep i'm in Sydney. Sounds like the shift kit is just better for any use type - right? I probably wont worry about the cooler tho since full synth fluid handles high temps so much better than non-syth stuff, and I wont be driving the stag too hard.

The trans will be fine in winter, it just needs a helping hand in summer really, to cool the fluid down and help it last. Heat is what kills auto's.

I would recommend the shift kit for any M35, however it's driven. The stock pressures are very low for comfort and soft shifts, but that is what promotes clutch wear. If the clutches go it could cost you 3-4 grand for a build, unless you can pick up a S/H one to replace it.

    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
