Mysterious Pfc Missfire In An R32 Gtr

[nobby]

You cannot always see a cold solder joint....might as well do it while its open, and seal it back well to avoid moisture getting in

x2 on that.

It may even look good.

but take a magnifier glass to it and you may see a what looks like a crack at solders edge,

again this is a poor joint and needs fixing.

Car R32 GTR 1994 JULY build...

Mine only happens maybe once every 200-500km or 3-6 days Very random and unpredictable. It happens rarely which is why I have not been so keen finding this problem specially when I see so many people having it and not one person finding an official solution.

Guys my aim is to one day fix this issue, whether it be changing to a D-metro or a whole new computer all together. Is there anything which is better then the PFC for the GTR other then the D-metro?

I am slowly changing every nut and bolt in this beast But ofcourse my aim is to get rid of the bugs 1st if possible. Car is not stock , -5s , Cams, AFM, Injectors, Fuel P, Coil pack-SF's, Gearbox etc... All internals are still stock and I am running at a Safe/healthy 330awkw.

I really want to get to the bottom of this now.... Im in sydney is there anyone wanting to chat about this seriously?

it's not d-metro its d-jetro. the stock pfc users airflow meters and it is l-jetro and the map sensor version is d-jetro

its likely the d-jetro has the same issue as its just map sensors instead of airflow meters

D-metro is the most manicured ecu of the PFC line up...

Where does the missfire occur? What plug gap? How old are the O2 sensors?

[GTRAAH]

Not sure where the miss fire occurs? What do you mean Have you looked through this thread its the same weird thing some people have with PFC, its like a microsecond surge of NO POWER. Hiccup..etc...... o2 sensors are not old at all, this is not a daily.. I basically changed all the wear and tear bits at 90k now its 96... dOne the 100km service and I am pretty sure the 02 sensors were changed whilst getting tuned either way I have not anyone talk about old 02 sensors in this thread. How ever my alternator is Very week its on 11.5V whilst driving I wonder if this may be the reason... Then you would think it should keep happening constantly not ev

every 200-600kms right??

neway

I have a RH9 130A Hyper alternator coming in the next couple days.

Has anybody solved the problem??

[GTSBoy]

Car is bloody lucky to run!!

How ever my alternator is Very week its on 11.5V whilst driving I wonder if this may be the reason...

[GTRAAH]

LOL funny you should say that, Its been weak since I can remember I bought it in 2006 first buyer in AUS Build Date July/1994 68k Speedo. It used to sit on about 12.6-12.8v then slowly dropped .So even then it was weak, I was told it should be between 13-14v while driving. Anyway now it varies between 11-12v Not very good the other day the volts kept going up and down 10.6 -11.5 And then all of a sudden my power steering cut off until I stopped the car waited a bit then drove again. Went back to normal and voltage stayed around 11.5 but this is when I went online and ordered a hyper alternator.

Anyways So the mysterious missfire any one manage to get rid of theirs completely with the PFC?

lol d metro

mine does this random surge, new plugs, new z32's, new injectors, new splitfires, only does it while cruising like most other ppl
