So i researched and have come down to the aic valve is either broke or needs to be cleaned. My NB has a really rough idle when i start it up cold to the point of where it almost stalls out on it's self. But once its hot and i turn it off then back on its fine the idle is just a little high. Ohh yeah and when its cold and i try and take off it bogs down on its self but once its warm its fine again. Am i on the right path here in cleaning/replacing the aic sensor?
