This problem has been around since last winter. When I start the car in the monrning it is 35degrees F outside. If I leave the trans in park it will idle at around 1000 - 1200 until it warms up, and then it runs normal. If I try to put it in drive before it warms up the idle drops off until it dies. This takes about 1 second. If I put it in drive and quickly give it gas it accelerates with normal power but when i get to the first stop sign the engine will die before the car comes to a stop. After a couple of miles it warms up and will idle as it should. I have replaced the IAC valve, and the engine coolant temp sensor. I have also taken the fit valve off and cleaned it. It has had a full tuneup and all fluids changed. Since it will idle in park like it should but dies in gear but only when cold I am beginning to think the PCM. Any help would be appreciated.

I just pulled it off and coolant is flowing out of it.

As an afterthought if the valve froze wouldn't it affect the cold idle in park also.
