HI All

so i got my new splitfires today, put them in, ran 1.0mm gap, and getting missfire at the usual rpm 4500-6000. Only running 10psi of boost, had no problems wiht old coils at 0.55-0.6mm at the same boost,

SO WHAT THE HELL. The reason i got these is to stop the missfire and increase my gap to increas mid range pull and fuel ecconomy, so gapping down is a bit of a waste of my money.

Is it possible that the earth might be a bit crap or something?

CAN somone advise me ASAP please

It's a series 2 with no ignitor. In regards to bigger problems, what else can it be, could the problem be a CAS sensor or something else.

I am going to regap to 0.8 but this sux, hopefully i can sorgth it out.

I have no errors on the computer, it has been tuned, new pump and so forth, the car did not miss at 0.55 gap, but the coils were shot, i mean i could hardly see the spark.

Sorry should have explained. When i got the car stock it was ok, but soon after i saw some cracks in the coils so i silliconed them up and they ran for a bit and then got worse. SO i gapped the plugs down till they worked wich was 0.55mm.

I am running the copper plugs that everyone gets on here, the BPRS6 things, NGK, you know the ones.

My fuel ecconomy started to suffer as soon as the coild started to fail, so i am trying to fix this by trying biger and better coils with bigger gap.

Thats not the right plug code... you sure thats it?

There are a few that are similar.

If you gap them down and its working, you have a faulty connection somewhere and isnt letting the power through

Find the cyclinder thats misfiring and it will be easier

Well series two with ignitor, did check with MM, and primary is 1.4k ohms, wich is standard for series two, series ones are like .6k ohms.

AFM is clean did that, just finishing the plugs and see how it goes.

BTW i am on my lappy next to the car while working so hence the responces on the run.

OK so

gapped to 0.8mm, still get a slight miss under 3 full load, bugga. I guess there must be something else wrong, not sure what though.

Any ideas. If my engine was getting crappy earth, would that cause problems?

ALSO installed an R32 wastgate actuator, and DAm, doe the car pull much better now.

HOWEVER also noticed with the splitfires, the car idles better, more pull through the midrange (this was before the actuator), and easier starts.

SO all i need to do now i figure out why it might still be missfiring.

I read somwhere that if the CAS is playing up that might cause some issues.

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
