Thanks for mentioning your issue. It sounds similar except that my car runs normally with good power and no surging (except for the effort required to get the cold transmission going). I am going to have to research this when I have a chance to get the car running in this state, and then see if I can isolate the cause. I know that there are no leaks, so there must be some switching thing or something sticking that is causing this. I also have a code reader so I will check that aspect as well. I made my initial post with the hope that someone would have had and fixed this problem so I would not have to do real work. Now I guess I will just have to figure it out! I will keep you posted.
