Favour - Borrow Some R32 Coilpacks That Are Known To Work

[Sarumatix]

I'm in a bit of a bind, I have new coilpacks and a miss fire at 4000rpm that screams coilpacks. Does anybody SE have a spare set of known to be working r32 coils I could chuck in to test?

*sigh*

I got my stockies but they were misfiring after a long drive

I'm sure some of them would still be good although not sure which one...

Let me know

[Sarumatix]

Took them out of my rb20.. it isn't the coilpacks .

[Sunkist]

Probably the igniter pack..

[Count Grantleyish]

It isn't the igniter pack.

[Sunkist]

Lol doesn't have one?

[Count Grantleyish]

He tested it before, the misfiring is still there.

[KURAUN]

Could it possibly be the coilpack loom? I've known a few times this to be the cause too

They go all hard a crispy after heating up so much after time, and some of the clips break etc

[Count Grantleyish]

Told Dave to check it few times, he said it's basically at same age as his coilpacks which is a year old or so.

Think he's trying bcpre7s plugs next.

bcpre7s plugs

Your problem may well lie somewhere here. 7s are possibly too cold, try some 6s.

He's having issues with 6s at the moment gapped with 0.8mm

[Sunkist]

Maybe boost blowing the spark out?

[blind_elk]

Then try opening the gap. New coils should be able to jump a 1.1 spark gap (assuming no major increases in boost are happening).

[Count Grantleyish]

He had 1.1 gap that was misfiring, changed to 0.8, same story.

He've tried another coilpacks, igniter to no avail. Dave has put up a thread on forced induction with detailed problem.

[Sarumatix]

Yeah i'm not trying to be difficult and be obscure, there is another thread (although i'm open to more ideas tbh this is killing me).

It's a misfire at 4000rpm under load when hot. Boost is 14psi. Car has been running fine, misfire appeared towards end of 5000km service interval so I assumed it was just old plugs which were 1.1 gapped. After replacing with 0.8mm gap it hasn't gone away.

It definitely isn't coilpacks, igniter. I am confident it isn't the loom it's new and not old and shitty like many I have owned that I had troubles with.

Gap, can try going back to 1.1 except everyone is certain that 0.8 should reduce misfire problems...

So that leaves me with fuel pressure (I have an 044 intank which could have packed up and given up, they arent' meant to be mounted intank). My workshop has recommended i check the pressure at idle.

Charge air measurement (haven't had any issues with these AFM yet but it could be one of them being a prick). I can check this with consult.

if it isn't those two things, i'm scared, and out of ideas . Thanks for your all your suggestions.

[Rekin]

i only had misfire when car was hot and revving above 4000rpm. Just like how you described. Removed coilpacks, inspected and looked visually fine. (no cracks etc). Mechanics were telling me its not coilpacks either.

Ended up replacing with brand new splitfires and problem was gone.

Unless you have tested with a brand new set of coilpacks, i wouldnt rule them out just yet...

[Sarumatix]

I tested with a set of splitfires from one of my other skylines that is currently driving around just fine. Not sure you can get a better test of coilpacks? Not only that but these coilpacks are literally new genuine nissan units... really hard to believe it is the coilpacks.
