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.
