R33 Rough Idle And Stuttering

Hi Guys.

Hopefully someone can point me in the right direction of solving such a seemingly insignificant problem.

Car: ECR33 GTS-T 186XXX km's, running 10PSI with bleed valve, Simota Pod filter, Gearbox Oil and Engine Oil + Filter changed less than 500kms ago.

When stepping on the pedal from idle lightly, the engine stutters roughly and then raises smoothly. The injectors tick/ tap like crazy and seem to have gotten louder in the last 1000kms and wasn't rectified when changing the oil? - if that matters at all.

When cold and gradually accelerating from 1000rpm to 3000rpm the car feels like it jutters forwards sometimes, like inconsistant power and is spasmodic in nature and minimal.

I don't have any experience with altering timing etc. but from what I have read I think this may have something to do with it. Also, the injectors are original and I have run Nulon fuel system/ injector cleaner through with a slight difference. Plugs have been cleaned and are not fouled up. Coil packs have been cleaned up and sealed using epoxy resin to cover cracks etc. with no misfire on boost :O I have cleaned the AAC valve and this has done nothing at all.

According to the previous owner, the O2 sensor in the dump pipe has been replaced - it doens't look like the original, although I am sure that the sensor in the cat has not been replaced.

Please help anyone! -

but below are just some fix.....

try cleaning ur iacv..using some good carby cleaner/throttle body cleaner.....

that made alot of difference on most people skylines...

and also try cleaning ur afm out..using a good electrical cleaner....

other than that theres not much else you can do...

check ur spark-plugs...make sure there regapped to 0.8mm...

make sure u dont have any vac. leaks...

and have u got the standard blow-off valve?? atmo bov causes idle issues...

and last but not least get a tune...

'bumble_bee' - Thankyou very much for the reply. I will check my bov - apparently it has been modified in some way and I will make sure I check the plugs as well - they are at 1.1mm. I will be getting a tune done too I think :ermm:

If anyone else can help, I would be greatly appreciative.

Thanks.

      Cleaning my wheels 😍

      By Milkmun · Posted

      Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.

      @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣

      Modern oils are amazing. Add tyres to that as well.

      Probably a smart choice to buy one vs build, purely for the motivation part as you said! Imagine the metal dust everywhere from grinding all the steel to build one. Ha ha ha!   Also, post a photo of your garage.   Mine is below, this is where I've been cleaning and have already half filled a caged 6*4 trailer. And this is after my cleaning expedition mentioned previously... The middle normally has a car in it, but I'm dumping things in the middle as I sort through them. And poor skyline was dusty and has had the lightest few drops of rain and now it looks atrocious and needs to be dragged back out and washed thoroughly! And yes to the right is technically another bay, you really can only see 2 bays out of 3 in this picture.

      It's more like on average the things I see a lot of things going wrong. Yes, usually the people who reach out are the ones who are having problems but on average it feels like mechanics and tuners here aren't really competent. I swing between thinking my standards are just way too high and wondering whether people really are just this dumb. I just had the strangest 10+ reply argument on a Facebook group over someone insisting that the factory R34 GTT boost control solenoid reduces boost pressure to 5 psi when it's on and raises boost pressure to 7 psi when it's off despite showing the exact plumbing in the factory service manual and the solenoid behavior detailed in the FSM.
