My intake been sucking air by itself why its in neutral as if i was lightly stepping on it. does anybody know what the problem is cause it never did that before?

 

If you are talking about that "hiss" of air, it's supposed to sound like that. Maybe you never noticed it before?

 

like the rpm keeps jumping up and down? vacuum leak, dirty/bad iacv

 

can you be a little more specific?

 

Is your idle at 700-1000~~ rpm???

At idle it should suck in some air so u should hear a bit of it at a stop.... (I don't remember what a CAI sounds like at idle )

But if it's really loud, check hoses and tb cables....

 

does it sound like this (the begginging of the video)? http://www.youtube.com/watch?v=0jcn4Qd5Mcw

 

that hiss gets annoyin after a while....specially when my cars cold n its around the 1200....(is that bad by any chance?)

 

do you have the ac/heater on?.. mine gets louder off and on at idle when the fans or whatever kick on..

 

Probably a leak. Retighten the clamps that came with your CAI. Or you can spray blake cleaner where the intake connects to the throttle body (if the brake cleaner gets sucked in, you will know you have a leak cause the engine will kinda stutter). You can also do this to where your intake and air filter meet. Good luck!

 

no its idle between 700 and 1000rpm. but when i lift the hood and listen to the intake it sucks air as if i keep tapping the gas pedal lightly every 2-3 seconds or so. im starting to think its a leak too but dnt really know how to fix it.

 

well. first find the leak, touch and move every hose around the intake, and make sure the clamps are on tight.

 

An easier way is to spray some carb cleaner around the fittings. If the idle changes you found your leak.
