hey guys, this only happens on a COLD start, as soon as I start the car i would get a squeaking noise for about 10-15seconds then stop. This ONLY happens on a cold start and sounds like a belt squeaking?

This 2nd problem is not related to the 1st. The problem is that i get low idles sometimes, looks to be about 550rpm, I beleive the correct idle range is 700rpm, and at other times i would get HIGH idles, around 1500-2000rpm, this dosen't happen ALL the time but does occasionally. Also Sometimes when i start the car, (dosen't happen on cold starts), the idle would seem to want to die but kick itself up then become stable. I read somewhere this COULD be from a split vacuum hose? but i am unsure.

Any pointers guys?

I drive an NA r33 gts4

The hunting is normal. The limits might be a bit extreme which means as above, clean your AAC and maybe even your AFM - use electrical contact cleaner for AFM and carby cleaner for AAC. Check for any air leaks with hot soapy water through any vaccum hoses

That noise is definately your belt. tighten it, spray on crc, or replace it (do others at same time)

Has anyone actually solved the cold start problems (low idle, having to stab the throttle to start in the worst case, high pitch sqeals) in skylines. I did a quick search and found heaps of threads on this, everyone says to clean the AFM and AAC but this does not cure it

i actually get a similar 'cold start ' effect when i havent fired her up for a good 3 days or more. When i first crank it over, revs will bog down under 300rpm for a split second or two and will then hunt its way up and up. I dont reckon its too much of an issue Matt, unless your car actually dies (on repeated occasions) if you dont stab the accelerator.

I did also have the squeeling belt problem too; tightening the belt up did get rid of the problem. That squeeling doesnt sound too nice ay!

The sqealing was horrible, mine only did it when I would crank it over too long trying to cold start smoother, I had a belt replaced recently which was fitted a touch too tight so thats all fixed.

The skyline cold start issue has gone on forever, personally, I have to give it throttle otherwise it catches and splutters between 0-500rpm and will never rev up but yeah it isn't much of an issue

1st problem

I have this same issue with my car

But, mine just had a major major service done and now starts to do it

So im suspect the belts are a bit loose,

they were all replaced and now are new!

but yeah i think i need to take it in to have them tightened up

    • Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.
    • At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!
    • Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.
    • Thanks GTSBoy, i will do abit more digging. I am missing a blue relay near the ECU connector... so i will chase that up in the next few days as well  
    • https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
