Why does my Nissan Altima sputters when I sit at a long traffic light?

My 2001 Nissan Altima, sputters when I sit at a long traffic light. I have had the throttle body clean, the air/fuel filter replace and a tune up. One thing mentioned was that my car should use NDK spark plugs, but I do not have them.

My car never stalls, it only sputters. But when the air conditioner is on the car idle is smooth. Any ideas?

Thanks! A: I know that my truck stutters when I use cheap gas. Maybe that might help.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
