Here lately my car seems to sputter ever once in a while..it is barely noticeable....and sometimes when i let off the gas my rpms will kinda bounce a little..like lets say it was at 1500 then it would bounce back and fourth from 1500 to maybe 1700..its weird but i can watch the needle. Anyone have any clue what Im talking about or have any idea what could be wrong?

This seemed to start a few weeks after I installed the 2.4 intake mani.

 

Could be something to do with your maf,Did you by chance touch it with your fingers when installing it in the new intake ?

 

I didnt put in a new CAI I put the 2.4 intake manifold on my 2.2

 

Those of us with the ss/sc have an issue like this, cleaning the throttle body fixes it. It might just be that your computer has to learn the new air flow from the manifold tho
