I can almost guaranty it's your throttle body. Clean it as well as your maf sensor. You can go to walmart and buy a little kit that comes with both cleaners for like 6-7 dollars. A new fuel filter wouldn't hurt either. The throttle body being dirty is a cause of a TON of issues on these cars.

 

same problem, i actually just posted this same problem

 

My 14 GT only does this if i dont let it warm up properly. (idle for 45 seconds before pulling out of my parking spot). when the vehicle is idling, and the revs start to dip, the ECU reads this and forces the throtle cable to pull, causing the throttle to add more air, again causing the engine to rev and not stall. something is not connected right. did you install the CAI yourself? a pro shop do it? I know with honda's the vehicle will ALWAYS rev and dip every few seconds. like 500rpm>1500rpm>500rpm>1500rpm every couple seconds and that is caused by a vaccuum hose leak or not being connected. Is it a manual or auto? Alot of companies ask if the new CAI is a Manual or auto due to an extra hose being needed on Auto transmissions.... let us know.
