Hi Guys,

Has anyone earthed Pin 60 from the PFC in order to fix the dreaded R32 GTR Misfire issue?

I just want to know, when you earthed it, did you cut the wire entirely and earth it straight from the PFC? Or did you splice in an earth?

I tried splicing in an earth and the car started to idle very roughly and i'm a bit cautious to cut the wire entirely to test a direct earth.

Thanks,

Taran.

I was told by other skyline people that running other than OEM coil packs can cause the hiccup. But I don't think so... And another thing I've been told was that the power fc needs a constant voltage and if it drops below that then it causes the hiccup.

But I can't confirm or deny any of that sh!t.

Alright guys. I grounded pin 60 directly using a very clean ground and it failed. It made the idle really lumpy and rough so now i'm back to how it was before.

Anyone have any other ideas?

The capacitor sounds interesting. How would we implement it?

Update. So i drove the car yesterday and the misfire is gone. Will have to drive it a bit longer to confirm it but so far so good. If it's permanently gone then it means it was the ignition fuse, near where the 4wd fuse is under the bonnet. The new fuse i picked up from SSS Auto looks like a newer type, it sticks out a bit more and the fuse link looks much fresher than the previous one. Perhaps this could have been it? What kind of fuses do you guys have in yours and what model GTR's do you have?

The fuse thing could be the fix. Maybe after X years they get brittle.

I put a USB charger in my ciggy lighter, and when u plugged a USB cable into it the fuse blew. Thinking it was a broken item to start with, but tested it again with a brand new fuse, and its been fine ever since. So it is possible that maybe the fuses are causing a bit of resistance?

      Change the transmission fluid. I would try Motorcraft XT-M5-QS if you have it in your area for a reasonable price. Also, double check your clutch is fully disengaging. If you are not pushing the clutch pedal to the floor fully for every shift now is the time to start. Make sure the clutch is fully bled. The damper line requires two distinct bleed points to be purged of air or it will not disengage the clutch properly. If either hydraulic cylinders input or output are losing hydraulic pressure in their seals/leaking you can have problems like this. If you've ruled out everything else then the most likely explanation is the synchros are worn and you need to double clutch the shift or rebuild/replace the transmission. The transfer case is discontinued FYI so you may want to rebuild it while you're in there too. If the chain stretches past spec it can do a ton of damage.

      My answer would be, that depends. If it's something that can be grumpy to start, runs a bit rich, and is likely an expensive engine, then yes, I would. But there's a few reasons why. Sumps aren't really sealed, there is airways to them, so it is technically open to moisture. Secondly, if as mentioned it has been started, and it's a fuelled up, I'd dump it, as chances are, fuel is in the oil. Next to that comes, how much use had said oil seen before it was parked up. IE, how much carbon, and potentially fuel/water did get in there while it was being used, and has now been allowed to sit, and slowly come together? For the most part, if it's just been something like a road car, stock engine, nothing wild, f**king send it if it's not near oil change spec.
