I have been having some seriouse issue with cold weather start up lately. when I start the car it will start right up but then idles real rough for about 2 min untill the car warms up. The idle dips and and rises and but then becomes stable once the car warms up. I have replaced the CCV as well as the upper and lower intake boot both of which had tears in them but the problem still persists after startup. I also cleaned the ICV and Throttle Body when I did the CCV, once the car is warm however it runs fine. I have the new O-Ring for the DISA that I have to replace and then maybe the hose from the air pump to the air pump check vavle. Hoepfully this solves my problem and I will repost back but I am also going to check that hose on the air pump to see if that is really causing all my issues since i havent purchased that part yet. Since it is on the top of the emgine I can remove and inspect it.
