My 09 maxima will sputter at idle when I come to a stop it will not do it if its in park. It will idle then dip down a hundred rpms or so then come back. It is not constant. All I have is a KN intake on it but do not recall having that problem before I put that cai in. Has anyone had this problem or ideas what it could be?!

 

Did you do the idle relearn after the install

 

I have not, how do I do that?

 

Run a good fuel injector cleaner through the gas tank.

 

Already tried that. :/ Guess I'll try this idle relearn. Has anyone done it before?

 

Use the search, I forget the steps. I did this with another nissan before after installing a intake. Sorry I'm not a huge help but tried to find a thread with the steps but couldn't. I believe it's the same steps though as the 6th gen
