Hey guys I was wondering if any of you guys had problems with their idling when you changed the PCV valve? I just did a recent oil change with the PCV valve change and now the idle will drop to like 500rpm when I make a full stop. It also tends to do this when I'm at the stop and move my steering wheel. Could it be the I need to adjust my idle control valve/screw or the PCV valve is $#$ked up? What do you guys think?>

I have the same problem with my car, when I hit the brakes it drops a little more, I'm pretty clueless as well.

IACV i think its called

little screw in the TB??

im pretty sure that controls the up/down idle u hear soemtimes on cars when they wont idle at a steady rpm

i have the same situation, sounds like a vaccumm leak, check your hoses

they probably didnt put in the pcv valve in properly. If its not in all the way it will idle funny

vaccum leak at the pcv it probably isnt installed correctly the hose may have a hole on it or the pcv may be cracked dont mess with your idle screw it will only mess things up.

greg you have a vacuum leak

Mono, you prolly have one too.

You should both prolly check your cars for carbon fouling in the throttle body that may be restricting the IACV. Do NOT adjust the idle screw unless you've changed your throttle body!!! That idle screw is set at the factory on a flow bench and the ECU is calibrated for that particular airflow at idle. Don't mess with it.
