Hey,

My r34 recently developed a hesitation around 5krpm to around 5500rpm and I believe it is most likely the afm. Is there anyone in Brisbane area that has a spare afm or working one that I can test to see if this is definitely the problem? Let me know would like to confirm the issue asap should be a 6 pack in it for whoever helps.

Thanks

Usually if its a coil pack you can see the damage...

It will fire the spark out the side of the pack to the cylinder head, leaving a "char" mark on the side of the coil pack...

Its easily spotted on the dyno with the lights off, its like a lightning storm under load at 5000rpm...

Just check the plugs and as you pull the coil packs inspect them closely...

A set of platinum plugs will set you back over $100, a set of new coil packs I think are still about $500-$550ish...

Here is way old-school thread i did where I had the same problem on the dyno --> http://www.skylinesaustralia.com/forums/topic/116653-a-day-with-matt-spry/page__hl__matt+spry

Thanks for that mate. I have heard most people don't bother with platinum and actually prefer using copper plugs and replace them more often.

Haha that thread is awesome epic story man definitely a top rap for Matt Spry also never heard of a shop doing something like that for a customer

    • That ring thing is interesting how it's holding everything together 
    • Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.   Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?     also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here.      also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system?    any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance 
    • Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel.  One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch.    These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height.    There is a lot going on in this picture and unless I did the job myself no way to tell what really happened. 
    • I did this mod in 2019  You just have to modify the top bracket of the ABS/TC/Fuel Pump Control ECU so it sits more upright and closer to the back seat and run a good quality positive battery lead from the engine bay, the negative lead i just bolted down to the body in the boot.
    • Damn... Not the feedback I want to hear.
