Today out of the blue, my car started idling funny, Ive never had this happen before on any of my other skylines, but it kinda sounded like I had rotational idle/lumpy cam. It also mysteriously brings the revs up high when they get really low down. On power, the car goes hard and seems fine.

I made sure all the coilpacks were in properly, however I have a feeling it could be spark plugs. But if it were spark plugs, wudnt the car drive like a bucket when i put the foot down? I checked the vac lines and it seemd fine as well.

Please help guys.

It could be also charcole canister.. I had same problem at idle with revs going all over the place (max 1500rpm), until i changed my charcole canister..

It did fix the problem however once in a blue moon, it still does it..

But then i think its something to do with my turbo-timer as well!! when i arm or turn off the car the revs jump all over the place.. but only in a blue moon now..

Hey guys i only recently bought my skyline and have had this problem now since ive had will clean the connectors on the air flow meter and hope that fixes it!

Everyone on the site that makes there input has helped so much (eg. stereo install, turbo timer, gauges, etc.) and its good to see that everyone helps eachother out.....

If I have a prob this is the best resort!

Cheers,

Dan

:P

Oh ok sweet I used throttle body cleaner in it today and it worked a treat! But now the car is missing a little bit on idle (like every ten to 15 seconds just pings a bit) but i guess its the fuel system. Some injection cleaner should do the trick!

Cheers

I have an HKS Electronic Idle Stabiliser for sale if you want it? It's used, but in 100% working condition.

HKS idle stabliser only helps when you have a big turbo and coming off throttle the afm sees different afm signals and causes the idle problem. The stabliser just changes that signal to a stable decreasing one to stop the idle problem.

It wont solve any other idle problems.

I have a cold start airbypass valve problem that keeps my idle at 1500rpm most of the time as the spring has come off the cold start bypass which keeps the revs up when the cars cold. Its a bastard to get to on the rb25 so i havent bothered to fix it yet since i hardly drive it now anyway.

thats what i hate about my f**king 33!

Its never right and its always 1 of a 1000 f**king things that could be wrong!

My dad is a mechanica and he hates the f**king thing!

Does anyone actually report that there 33 is fine and they dont have many dramas?

f**k me!

OK,

I cleaned AFM, new spark plugs, new fuel filter.

Nothing, still does it, however When i was hammering it It would fix itself sometimes. It still is just as powerful and goes hard.

Its intermittent.

I dont know what to do, is it a air leak, coilpacks, vac leak its doing my bloody head in.

Ive tried dissconnecting the coil plugs on at a time and all that does is drop that cylinder and make it sound like a WRX.

Its just got a bad idle, sometimes like Rotational Idle, sometimes just lumpy.

I havent tried the cleaning the AAC valve yet, you think this is causing the problem?

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
