I was searching the forums about poor idle on the 2.5 Nissan SER Spec v, quick notes: the car is 2002 with 31K miles. I’m running the NGK plugs, car well taken care of, normal oil changes and upkeep.

I have had an AEM CAI for some time without any issues. In the mornings, when I go to warm the car up, I let it do it’s thing to just under 1k rpm before I leave to work. I noticed that the car idles at the rpm that is should, but it just isn’t smooth. The idle seems erratic. It’ doesn’t bounce all over the place, it just is not smooth! It isn’t until I actually drive the car a little, or down the road a bit, when the rpm finally smoothes out.

Question: why when the car first starts out, you know, just getting up in the morning to go to work, is the idle not smooth? Second, why would it take a little driving down the road to smooth out at the stoplight all of a sudden? It doesn’t make sense. Is it the computer, sensors, doesn’t know what the hell to do during cold driving/mornings. It goes through this same routine if it be 30 degrees or 70 degrees outside…suggestions anyone..
