Hey guys,

 

Sometimes when I start my R34 GTT (98, NEO) it sounds like its stuttering or spluttering, but it starts each time. Then when it gets warm and I'm sitting at lights or just idling, the revs will go up and down and low enough sometimes to almost stall (but it hasn't yet). I have no idea what this could be, I purchased a new Z32 AFM and installed it, but the car ran like shit as I'm guessing it needs to be tuned for the new one (so I put the old one back in).

 

Help is appreciated :D 

Yes, well, you can't run a Z32 AFM against a standard ECU without Nistune, correct.

I would suggest that your IACV would be dirty/sticky/blocked, hence the engine's inability to control revs. But all the roughness could be just about anything. AFM (dying, dirty, broken solder joints), CAS (same), injectors (dirty, broken loom plugs/pins), coils (same).  The list goes on.

When I got the car looked at by a mechanic (it had a check engine light) they said the light was from the throttle actuator or o2 sensor. I'm guessing this is related, but what does that mean / what would be the fix? Sheesh

 

The car also idles at 1100 rpm

Link is dead, and the official Nissan mechanic wasn't sure either, he also said 'a retune will probably fix the issue' but I don't think that's true

    • So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.
    • Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?
    • Should have asked what is the car?
    • I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.
    • Hey guys,  Way back when (about 15yrs plus), I picked up a beautiful set of Tein 'Super Racing Spec Circuit Master RE' coilovers from Russman. I have legit never fitted them to my car, as it was garaged indefinitely while i bought a house Yada Yada. They look brand new! Anyway its time to pick up where I left off, and have started doing some khanacross and am booked in for a hill climb next month. The car has some hard af Nismo shocks in ATM, which has me wanting to upgrade again, and now I am left wondering if it's worth having these teins rebuilt? I think they where an ok shock back then, but how do they compare to what's on the market now?  Shockworks/mca are 2800+, and I am sure they are great. But if I can have these rebuilt and be better than, say, a set of bc's for around the cost of bc's, I would be happy with the performance v cost trade off.  If they are considered outdated and rubbish these days, so be it, I'll put them on the shelf and be happy to look at the pretty green colour while I save for the SW/MCA option. Grateful for your thoughts on the matter, and suggestions on who could do the rebuild if it's a worthwhile pursuit.  cheers, Rowdy.
