when it was new it was around 800 but now it dropped down to 600ish. (a little above 500)

i can feel it stalling out a little like its not getting enough gas or air.

i just got a K&N air filter and its a manual.

is it natural?

 

How many miles do you have on your car? Mine did the exact same thing and I wanted to adjust it but due to electronic throttle body I don't know if it is possible. I did clean the MAF sensor a few times and it helped a little, but still had a low idle.

 

I wish my car idled at 600...

 

Sounds about right. Car shakes a little bit sometimes but i got use to it.

 

its under 5k miles.

im getting a little worried since it can stall out if it drops too far.

taking off became a little harder =/

 

thats should be normal? car idles funny till warm up then it should be anywhere between 600-900/1000 rpm but its about right 600 is what my car idles at when its all warmed up. taking off is alil harder? thats normal ur jus use to the car being at 800 rpm and helping u move the car easier when u let go of the clutch.

all in all its normal no need to worry bout it my car idles at 600/700 and i have an 05 with no problems at all dont stress it

 

did u disconnect the negative battery after u put on the intake to reset the ecu...

 

Are you sure the k&n filter isn't over oiled? I personally would throw it in the trash and get an non-oiled filter or go back to a paper one.

 

FTW.

 

I've just recently been having the same problem myself but my car idles between 400-500 rpm as per my scangauge II. It doesn't do it all the time though. Kinda worries me a bit cause the car feels like its going to die. I have an 07 with 34K on it and as far as mods go i have an injen cai, nst pulleys, catback exhaust system.

Any idea as to why this happens?

 

if i remember right you can adjust the idle near the gas peddle... i seen it somewhere on this site but idk where it is now

anyone care to shed light on how to adjust this for these people?

 

My car idles 600-700rpm and pulls -24 hg/in vac at idle.
