how would the cat affect it?

update: i got home this arvo (been driving with the o2 sensor unplugged) and plugged the o2 sensor back in. seemed to run fine. then the aircon switched off, and it ran slightly crappy. turned aircon back on and ran fine. watching the gauge it runs leaner with the aircon on, and richer with the aircon off. so i'm thinking it may be fouled plugs, or possible the idle control, but i'm open to other suggestions.

Did you say you cleaned your Afm's..........did you open them up and re-soldered the joins?

Just curious........what colour is the shirt?

yes.......... yes.

thats ok........ blue

i don't think it is the throttle cable. the reason is that i can sit there and it won't do it. then it might do it for a second then it will go away. or it will hunt so bad it stalls the car.

i'm giong to clean the AAc valve again. last time i had this sort of issue it was the cause, but it had slightly different symptoms. it would hunt, but the idle would sometimes sit at 600, other times 1500.

i know it is digging a bit, but this morning my car a had a slight missfire for about 5 secs on really low acceleration. No boost prob still running - pressure in the manifold. The car had warmed up or was close to it, and it is the first time it has done it. It has not done it since, only that short time.

Just wondering MAD082 if you found out your problem? or if anyone knows anything new.

i ended up altering the tps, putting a new fuel filter in, cleaning the afm, changing back to my old o2 sensor, got rid of some vaccum leaks.......

i think that was all, and yes it did go away. i think the vaccum leak was the main cause. it was the breather hose on top of the rocker cover, and also the seal around the pcv valve that i found to be leaking.

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • 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.
