I have a 2005
MCS that has a little over 3000 miles on it. It was built in mid-November 2004. It is a great car but I have noticed recently when the car is cold and has not been started for awhile (sitting overnight), it will start fine and in about 5 seconds after start it will start idling low and almost quit. Then about 5 seconds later it will snap back into a proper idle. Has anyone had this occur ? I am wondering if there is a computer upgrade or something for this problem.
Thanks,
