ever since i took my AC out my b16a2 is idling really low at stop lights, almost to turning off. i have a skunk 2 manifold, and stage 1 clutch and 9lb flywheel but everything else is stock. is it cause of the stock header? throttle body? or maybe even spark plugs? if anyone has any ideas let me know

 

bump cuz my car is idling low as **** as well. but never cuts off or stutters...

 

not sure about the ac, but having a skunk2 IM hurts power, on a bone stock motor...something you may want to look into, bigger cams and better flowing exhaust...

what does it idle at? mine stock si idles at like 400rpms...

 

is 400 rpm really low still? isn't it suppose ot be 750?

Since when does it hurt power on a stock motor? Dyno results I've seen show 5-8 hp over stock and mine definitely doesn't feel any slower after the im swap.

To the original poster, I have the same motor, same im, and no ac, and the only time I had that problem was after the im swap. Try adjusting the throttle screw.

P.S.

Never do an open poll like that unless absolutely necessary.
That's the kind of answer you will get almost every time.

Adjust your idle...I believe stock idle is around 700-800 rpms. I believe there is a throttle/idle adjustment screw at the top of the throttle body.

dyno results i've seen shown to hurt power until upgraded cams and exhaust are added. but if you experienced gains, more power to you!

 

the hotter it is outside the lower my idle is....

 

Just adjust your idle higher. The idle is suppost to be 750rpm when at normal operating temp. After I swaped my stock flywheel (16.5lbs.) with my chromoly one (8.36lbs.) I never had to adjust my idle. I don't think the flywheel made the idle go down. Since idle is getting worse when the engine is hot I would say to check and clean your <U>IACV</U>, check your timing, check your PCV and then adjust your idle.
