I have been driving the car for about a week now and not had a problem again. It has Ben a little warmer in the mornings. But only about 10 degrees F. Just took it on a 300 mile trip and the car drove like a dream. I am going to take it in for new brakes and rotors next month and have the fluid checked again (per my mechanics reco). We will see if I have any more problems between now Nd then. I also reset the throttle adaption the day I posted this thread. Hopefully I'm good to go!!!
