Very Odd Idle Problems..

Hey,

I've got a rather odd idle problem with my R32 Gts-T.

I had been having a few peoblems where I would stop at the traffic lights and the car would pull up yet the revs would still be a little high. then after a few seconds they would drop to a normal idle.

Other times It would be Idle fine but then it would pick up 50 - 100 revs then drop then pick up then drop for a few seconds it would do this.

I thought It was my clutch slipping or something?

However Tonight as i was waiting in the Drive-Thru at KFC, I noticed that if i was stopped and turned my wheel full lock to the right the revs would drop from 800 to 100. and almost stall.

Maybe its got somehting to do with power steering? Im unsure but hopefully some one could shed some light on this for me?

Thanks,

Essential.

We had a similiar problem with our 33 (RB25DET), according to autotech its because the throttle body builds up a lining of "crap", which I seem to recall is from the gas recirc?

Either way, they '1 x clean throttle body' and the problem hasnt happened again.

This was most obvious pulling up to a set of traffic lights and popping the clutch in. The revs would die right down on occasionally stall. Other times, it was ok.

its a bit of a bitch to remove.. to actually clean *inside* the plenum.. but that could work. Cleaning AAC valve, etc is another thing to try.

Generally the idle revs can be a bit jumpy. In fact most cars i have had haven't had a perfect idle..

The skyline stock ECU has some kick back thing.. basically when i think it senses its about to stall it dumps in more fuel or adjusts the timing or something and the revs jump back up. So it can kind of "cycle" like that as you sit there. I wouldn't really worry about 50-100revs - i think that is fairly normal?

Although reading down about ur battery thread.. maybe your alternator is a bit dodgy, and having trouble supplying proper current. Maybe that is causing things to fug around like that. Check the belts and a few things like that.

I am really only just guessing here though, somebody would need to check it out properly.

      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!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      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.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      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.
