Help! I have purchased an R32 GTS25 and am experiencing some engine problems. These problems include; occasional missing, occasional stalling and the occasional hesitation (by which I mean when I am accelerating the engine almost hiccups, it cuts out then comes back in accelerating). I have taken it to the local Nissan Dealership who originally diagnosed it as a faulty CAS. So I got that replaced and it didn't do too much, just made these problems occur less. However they still do occur... So I took it back they performed another diagnostic check and the DTC came back OK....

How do I fix these problems!! They suggested coils (which I replaced with "newer" 2nd ones 2 months ago), Igniter, AFM or the ECU?? Which would be the best plan of attack? Or is there something they missed??

Cheers Rich

did the coils make any difference at all? there is always the chance that they were no better than the ones you replaced. the ignitor is also worth looking at (if it is a serious 1 r33)

if possible, if you have a mate that also has a r33 you could try swapping parts with his car and seeing if you can isolate the problem part

No cat converter so thats unlikely haha, and no I also replaced the fuel filter about 2 months ago aswell so again unlikely

Yes the coils made a slight difference but I mean it wasn't like it was a game changer as the problem is still there. No, no mate that I could swap parts with, but will look into the igniter as yes it is a series 1 RB25de

iv got a very similar problem wiv my rb30 iv replaced all the same shit including distributor cap and rotor , leads n AFM and the power transistor next 2 the distributor. some1 has mentioned problems with the actual throttle body not sure though. when it plays up can u smell unburnt fuel?? mine stinks of it wen it stars randomly running like shit

If I do (most probably) end up replacing my AFM what would be the best replacement? As am browsing through trademe and to me they are all the same thing just different colours :/

As long as it's green sticker it should be the same. Double check the part number on yours matches the one your buying. 22680-02U00-?

UPDATE:

Now my car doesn't start at all :/ It turns over but doesn't want to start, so I replaced my ignitor and resoldered the joints on my AFM (to try solve the original problem) but nothing changed, it still turns over with no motivation to start. Will be taking it into an auto electrician tomorrow hopefully.

    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
