Ok so today I decided to take my CAI off and put the stock system back in to see if it would help my idle. So I start the car up with the stock stuff on and it idles smother but it still has a miss. At random it makes a deep pop, I have replaced the spark plugs recently so what could be causing this?

Does it sputter when you drive? If so it could be the intake manifold or the manifold gaskets going.

Check the IAC motor (idle air control). These tend to get plugged with carbon. They are cheap to buy--around $70 at the dealer. Hope this helps!

I just watched a video of some one cleaning this and when he started the car is had a little poping too, Is this just some thing these cars do?
