I have a stock motor d16y7 for the mean time but im having problems..when the motor is cold it idles fine but as it warms up the idling gets lower to like 500rpm or less and when im driving and coming to a stop at a light or just a stop sometimes it idles very low and sometimes it just dies and i have to start my car again. it does that everytime i slow down or stop etc.. can u guys tell me what can be wrong?

 

It could be that your car is overheating and the idle screw on the throttle body is set wrong. Adjust the screw first, and if that don't work, replace the IAVC valve/sensor. I think your car is overheating though.
