hard starting when cold.

[crack]

hey all. my skyline has started doing some wierd sh*t lately. when starting from cold i have to press the accelerator a couple of times to get it to idle properly. the revs rise to approx. 1200 rpm and then it settles down to normal as it starts to warm up. i never had to touch the accelerator when starting the car before. just turn the key, revs rise up to approx. 1200 rpm then settle all by its self.

is there a idle valve or something similar that could be faulty or need cleaning?

thanx.

Same problem mate..

However when i turn my key on a cold start it burbles at around 500rpm like its gonna konk out at any second so i have to rev it over 1000rpm and it sits on 1200rpm..let it warm up for 3 minutes and it drops to 700rpm.

I think its pretty normal...my mates 180 does exact same thing. When u take it in for a service it should be fixed...not a major problem at all imho.

Exactly what happened to mine about 2 months ago and has been like that since.

Are you guys running stock ECU's? ... I'm no expert but I'm thinking a couple of things, from experience with my new set-up on the GTR which could be:

- lazy injectors

- sounds like a fuel source issue, maybe pump, fuel pressure

- what size "cc" is your battery the bigger the better.

- if you've got aftermarket ECU a tune should fix that.

S14 with same problem here!

Common prob. Have you thought that it could be the fuel injectors as meshmesh said? Crap fuel? Trial and error.

mine does this all the time

everything is stock on my car except for the exhaust.

I had the same problem, like real bad sometimes need to crank over 8-9 times......but i change my battery last week and it seems to have made abit of a difference.....starts without touching the pedal now. I had a battery which could almost into a torch.....now i got a 450 CCA. Century Battery.

Thats my 2cents
