when I first start my 87 pathy it idles kinda high (2krpms) drive it for a second and it goes down to 1.5 and then after I've been driving for about a half hour maybe a little less it idles nicely at 1k.
Any thought?

My 1992 has the same issue, idles 1100-1200 until it reachs operating temp then it settles down to 650-700 rpm I can hear a slight hiss until it warms up and I have checked everything that can be seen or gotten to. It sounds as if it may be coming from under the plenium at the air idle control, but I have just been to lazy to pull it !Chadius wrote:so I've read around other Nissan forums and they said it might have something to do with a vacuum leak I also hear the hissing sound they say you might hear if you have one, can anybody help me locate this? The car is pretty rusty so it might be a rusted out spot somewhere underneath.
Any help would be nice thanks.
