Yeah I had a troublesome one that kept popping off and making the car run like shiet!

Went right over the car last night and found a plug that was unhooed between dipstick and oil filter so I am hoping that might have something to do with it, I also found a lot of moisture in various plug connections so have dired them all out + I have pulled the afms out and will resolder the connections today!

Cant seem to work out which vacume hoses you guys are talking about? In and around FPR?

Thanks,

Dan

Different car, mine was up the back under the throttlebody (gtst plenum).

i dont really wash my engine bay as i dont want to risk getting water into my coilpacks so what i usually do is wipe it down with a cloth but if you have to wash the engine bay, avoid the top part of the engine. i even had to tell the mechanics not to wash an rb motor with degreaser and pressure cleaner cause we had one who made a mistake of doing that and the car was misfiring badly and he had to take the coilpacks out again and blow dry them and the car ran fine afterthat. you can wash and degrease underneath the car or on the oil filter (which is away from the coilpacks) but avoid the cam and coilpack covers at all cost.

UPDATE: Still running rough- poor idle / Blowing white smoke / loss of boost / power

I have spent all day again going over everything

- solderd up afms again (the car is definitely running smoother but no boost/power and a lot of white smoke)

- checked vacume hoses

- checked electrical connectors and checked for exposed wiring

- Pulled apart BOVS (these were caked with fuel especially in the alloy elbow connector? Can this happen from to rich a mix? Normal?

(Boost gauge 'standard' still reading 0)

- should I get out the multimeter and start checking everythings getting power

- I have got a nissan consult cable and software but no working laptop, would it be worth borrowing one if its likely to pick up such error codes that are affecting car

Would it be worth taking my coilpacks out again and checking for moisture as i only gave these a quick wipe as i couldnt see any moisture on them- only down in the spark plug area where water was sitting?

Ok I am really stumped now so I'm going to mention everything i have done in the past weeks!

Changed my Pods over the other day from Hks mushy pods to some M's pods, i wouldnt need to reset my ecu for this would I? Running a BLITZ ACCESS ECU

Having my fuel pumped earthed at the moment meaning the pump continuously engaged- is it possible my injectors could be over-firing or somethings a miss with the FPR?

Thanks again for all the replys

Yeah mate up the front near the FPR and there is a little electrical connector near the hose I am talking about.

I pulled all the connectors out around this area aswell as plenum sensor thing but there wasnt a vacume hose? Not the one half-way down the intake plenum that connects into the head?

while u got the plugs out, do a quick check of compression

=] my rb had similar symptons as what your saying mate... wasnt lumpy but had smoke and that

cyc #6 was down a little.. i keep driving for a few days and noticed more whitey smoke

i mean the power was still there, until the last day when i decided to take it off the road.. coz i actually had oil blow back

and was running lumpy.

was my ring land had broke, melted to the top of the piston lol and most of came off during last day...

all due to running lean

Had my compression checked at workshop probably 100km ago and it came back perfectly consistent 150s!

Do you mean just with a handheld compression tester gauge? I havnt used one of them before but will see if I can go pick myself up one tommorow!

I am still convinced its something ive done whilst cleaning engine as the car has barelly been driven 100km in the last year and a half and had been running perfectly before clean?

      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.
