hey i have an r33 gtst skyline i seem to have problems with it.

when i start the car when its cold the engine feels tip top.

when i drive for a while and the engine satrts to heat up a bit it feels like the car wants to stall and has an idle problem.

when i turn the car on when its hot it takes a little bit to find its idle...

it goes from 100 to 1000 in reving and sometimes stalls when i try.

also when i rev my car a little it sounds like there is a rattle where the timing belt is.

it kicks in at about 1000 and cuts out a little later.

things i have replaced.

oxy sensor

tps

engine and turbo

mods i have

hks airpod filter

carbon battery.

i have video of it

also my throttle cable feels lose as you can see in the video.

$15 will be rewarded with correct awnser for both things that need fixing.

i will slowly replace items once i know whats going on.

on thursday my car will get dignostics done.

i only ask this because everywhere i go machanics are like agrrrr this is the problem but its not really agrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

thanks alex

I've got some money on the AAC valve, or the Cold Start Air Valve (underside of the inlet manifold). But if you've replaced the whole engine, then those would have been replaced.

Yeah sounds like your AAC is stuck open or the regulator is faulty
Pull the plug on and off to see if theres a drop/increase in revs.

What if there is a drop or increase in revs? Which is supposed to happen?

wow, we are in pretty similar situations, Ive done a rebuild, done the turbo and only got a pod filter. Yeah only rebuild the long block, so kinda sems like they gave me back this amazing engine block surrouned by sh*tty parts lol. my idle used to be all over the place, so i began replacing parts. i replaced the IAC valve,then eventually the whole unit, got new tps, got it re positioned, got a new throttle body and cleaned the unit out. That worked for my idle issues, never stalled or hunted around much again, only rarely. I'd also check for any vacuum leaks or cracked hoses, ask ur mech to do a compression test. rebuilt engines have so much power when everything around them is running right. also for your rattle, I'd suggest u check that all the bolts up font are tightened. Good luck wit it

Ben, I am currently having problems very similar to this and you said you replaced your IACV Valve and i have ben told thats what i need to do but i am having a lot of trouble finding out where to get one, Nissan don't want to sell me the valve alone they want me to buy the entire unit and that is around $1k for something i dont need, could you tell me where you got your new/used one from please? I have a 1996 R33 series II.

    • But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?
    • Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.
    • Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
    • Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
