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?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
