Car runs rough when it is cold?

SE-Rican · 01-16-2002, 04:52 PM

Ok guys this is my dilema. When my car is cold it sputters a little bit. What I mean by this is that it is a little hesitant, but when the car comes up to temperature it runs awesome. I did a motor swap and my old motor did this as well. I believe it could be some kind of temp sensor. I have had this problem for over 2 years now and finnaly it is getting old to me. Its not that bad but everything else on my car works pretty well and finally I would like to get this fixed.

Do any of you guys have this problem and do you have any ideas on what this could be. And also is the part expensive?TIA

I have this problem too, and HATE it.

The problem lies in 2 things:

Your Air Regulator Valve ($50 at nissan dealer)
Idle Air Assembly ($150 at nissan dealer)

those 2 items need to be either cleaned, or replaced.

my car doesent just sputter, it feels like it doesent want to be driven, but then, once the temperature needle moves up a little bit, she runs good. you can fix it yourself, probably, but i'm just going to buy new sh*t, *** i'm like that..

have the same problem, i just let it worm up. it's not that big a dieal to me. but he's right about those two things.. you might even see a performance increase out of cleaning/changing them. good luck....
