Not exactly but it appears the IPDM has sat for some period of time horizontally with water in it, im thinking maybe when the car was resprayed (it was already a non standard colour when i bought it) it may have sat for a period of time without the bonnet on it, the bonnet bolts were loose when i got the car, along with some other earths the engine mounts and a few other bolts... Ive since gone over just about every bolt i can find for piece of mind.

I checked the car over as well as i could before i bought it, ive had most of it apart since and i cant see any signs of a major accident, im told it was that colour when it came into the country so maybe just some dodgy jap panel beaters that did the respray?

Hmmm, a little less confident today, i went to the workshop last night and asked my mate who had been there all day if the car had sounded the horn or done anything wierd... As he said "no, not at all" it started beeping... i walked over and turned it off and then on again...

Perhaps its lonely having sat in the corner for at least 6 weeks and was just happy to see me?? coils have been shipped and should be here by the end of the week... only time will tell i suppose...

Well, coil packs arrived today, the boots on them were very dodgy so i put all the original ones onto the new coils. Started the car and it was evident it was missing on more then a few cylinders.. wouldnt even rev to start with, checked all the coil packs and all were sparking.. seems the injectors were stuck and all came good when it got up to temperature except No. 4... tried tapping the injector while it was running but to no avail...

Wasnt prepared to pull the manifold off tonight will have another look tomorrow, only error code showing up was a miss fire.. funnily enough.. going to do a compression test tomorrow before i pull the manifold off just to rule out the possibility of a broken ring, but i highly doubt that will be that case... At least it runs and my software talks to the car, just frustrated atm was looking foward to driving the bloody thing... Im thinking its just a stuck or blocked injector, well hoping...

Pulled the injectors out today and took them to a local injector cleaning place. The suspect one was blocked and apparently none of the others were flowing poperly which is a good sign that, that is the only thing left wrong with it atm... will know tomorrow i suppose...

Good Luck dude, pretty sure the whole forum has it's fingers crossed for you.

On the bright side - is there really that many more parts/issues it can be? :rofl:

The more time it takes the closer you are to a solution.

Cheers guys.

Well my patience is really being tested now...

Injectors all clean and nice and still missing on No. 4, it has spark and it has fuel it can only be a timing issue now.. I connected my turbo xs ECU and still the same problem which leads me to believe its sensor issue now.

Now these things use 3 sensors a crank angle sensor activated by a plate attached to the ring gear the sensor is mounted in the bellhousing, I have ordered one of these but it most likely wont be here till after christmas, and 2 camshaft phase position sensors, these the worshop manual tells me tells the computer exactly where each piston is in its cycle... I ordered both of these today and they will be here at lunch.

If this doesnt work i may set fire to the thing..

John,

How bad is your miss?

I have a tiny little miss when the car is idling but nothing noticeable at all when driving. I'm thinking mine might be more to do with the aftermarket exhaust.

If this was my idle pattern and 1 dot = 1 second, the gaps would be the miss i have

......... ......... ......... ......... ......... ......... ......... ......... .........

I'm not sure if you would even call it a miss.

Yeah its not as bad as it has been.. infact it pretty much sounds like what your describing.. and considering i havent heard and or driven it for that long, its definately not as pronounced as it was before i got the injectors cleaned but its still throwing the check engine light with a missfore error aswell as an unknown error. im going to take it for a drive tonight. i snuck away at lunch time and changed the sensors with the new ones and its still there. Just picked up a cheapo jaycar oscilloscope so i can now test all the sensors and triggers.. so if driving it doesnt fix at least ill be able to pin point the problem.

Well i left work early, took it for a drive, Complete miss on No.4 yet its sparking and has fuel... Unless for some odd reason the when the plug is in the head the power from the coil is not conducting through the plug?? i got nothing left, put the oscilloscope on all the sensors and there all reading correctly, there is good compression on that cylinder it has fuel and its wont f**ken run!!! im loosing my mind over this...

Well after looking at it a bit more the oscilliscope showed the no. 4 injector trigger to be running at less than 2 volts...

So i only have 2 options now.. some how try and source a standard computer, god knows how much that will cost or go a full stand alone ecu like the autronic... mmmm

Dude, give this a try. Maybe get in contact with the seller.

Not sure if it would be the same tune as the V35 but for $150USD it may be worth a shot.

The autronic should be here tomorrow.. Going to wire it up so the standard computer still thinks its running the car to keep the BCM happy... Been so busy with work the last few weeks, the riggers managed to damage all 3 CNC's and the manual lathe, idiots ah well. Yeah will probably wire it up next week... Should be good :domokun:

Thanks again for all the help guys.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
